eb199145 25* Installation Changes in Emacs 24.1
09e18d03 26
338648ad
GM
27** Configure links against libselinux if it is found.
28You can disable this by using --without-selinux.
29
30---
31** By default, the installed Info and man pages are compressed.
32You can disable this by configuring --without-compress-info.
33
aded53ff
GM
34---
35** There are new configure options:
36--with-mmdf, --with-mail-unlink, --with-mailhost.
37These provide no new functionality, they just remove the need to edit
38lib-src/Makefile by hand in order to use the associated features.
39
e547b051 40---
30c4d8dc 41** Emacs can be compiled against Gtk+ 3.0 if you pass --with-x-toolkit=gtk3
e547b051
J
42to configure. Note that other libraries used by Emacs, RSVG and GConf,
43also depend on Gtk+. You can disable them with --without-rsvg and
44--without-gconf.
45
d9170db5
DN
46** There is a new configure option --enable-use-lisp-union-type.
47This is only useful for Emacs developers to debug certain types of bugs.
b2957ea8 48This is not a new feature; only the configure flag is new.
d9170db5 49
d064e6a6 50---
f042970d 51** New translation of the Emacs Tutorial in Hebrew is available.

eb199145 56* Startup Changes in Emacs 24.1
4a263588 57
198a7a97 58** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte
adbf62ff
GM
59command line arguments, and the EMACS_UNIBYTE environment variable, no
60longer have any effect. (They were declared obsolete in Emacs 23.)
198a7a97 61
66b7b0fe
GM
62** New command line option `--no-site-lisp' removes site-lisp directories
63from load-path. -Q now implies this.
64
71edd0ec
JB
65** On Windows, Emacs now warns when the obsolete _emacs init file is used,
66and also when HOME is set to C:\ by default.

eb199145 69* Changes in Emacs 24.1
7841339b 70
3e2d70fd
SM
71** Completion in a non-minibuffer now tries to detect the end of completion
72and pops down the *Completions* buffer accordingly.
73
2a847524
CY
74** emacsclient changes
75
76*** New emacsclient argument --parent-id ID can be used to open a
0191e222
CY
77client frame in parent X window ID, via XEmbed. This works like the
78--parent-id argument to Emacs.
79
15a7a774 80+++
d862b746
GM
81*** New emacsclient argument -q/--quiet suppresses some status messages.
82
2a847524
CY
83*** If emacsclient shuts down as a result of Emacs signalling an
84error, its exit status is 1.
85
902a6d8d
SM
86** Completion can cycle, depending on completion-cycle-threshold.
87
3ec03f7e 88** `completing-read' can be customized using the new variable
f042970d 89`completing-read-function'.
3ec03f7e 90
2372f278
SM
91** auto-mode-case-fold is now enabled by default.
92
f4b6ba46
EZ
93+++
94** Emacs now supports display and editing of bidirectional text.
f4b6ba46
EZ
95
96See the node "Bidirectional Editing" in the Emacs Manual for some
97initial documentation.
98
99To turn this on in any given buffer, set the buffer-local variable
100`bidi-display-reordering' to a non-nil value. The default is nil.
101
102The buffer-local variable `bidi-paragraph-direction', if non-nil,
103forces each paragraph in the buffer to have its base direction
104according to the value of this variable. Possible values are
105`right-to-left' and `left-to-right'. If the value is nil (the
106default), Emacs determines the base direction of each paragraph from
107its text, as specified by the Unicode Bidirectional Algorithm.
108
d20e1419
EZ
109The function `current-bidi-paragraph-direction' returns the actual
110value of paragraph base direction at point.
111
f4b6ba46
EZ
112Reordering of bidirectional text for display in Emacs is a "Full
113bidirectionality" class implementation of the Unicode Bidirectional
114Algorithm.
115
46759717
EZ
116Note that some advanced display features, such as overlay strings and
117`display' text properties, do not yet work correctly when
118bidirectional text is reordered for display.
119
303500aa 120** GTK scroll-bars are now placed on the right by default.
52834b6b
CY
121Use `set-scroll-bar-mode' to change this.
122
20fe03ad 123** GTK tool bars can have just text, just images or images and text.
d8004abe 124Customize `tool-bar-style' to choose style. On a Gnome desktop, the default
20fe03ad
JD
125is taken from the desktop settings.
126
8b2dd508
JD
127** GTK tool bars can be placed on the left/right or top/bottom of the frame.
128The frame-parameter tool-bar-position controls this. It takes the values
1c0d77cc 129top, left, right or bottom. The Options => Show/Hide menu has entries
8b2dd508
JD
130for this.
131
8740c12d 132** ImageMagick support.
b2fa3a09
GM
133It is now possible to use the ImageMagick library to load many new
134image formats in Emacs. By default, Emacs links with the ImageMagick
f5b06c35
GM
135libraries if they are present at build time. This needs ImageMagick
1366.2.8 or newer (versions newer than 6.0.7 _may_ work but have not been
137tested). To disable ImageMagick support, use the configure option
fa6996bc 138`--without-imagemagick'.
16a91140 139
8740c12d
GM
140The new function `imagemagick-types' returns a list of image file
141extensions that your installation of ImageMagick supports. The
142function `imagemagick-register-types' enables ImageMagick support for
b2957ea8 143these image types, minus those listed in `imagemagick-types-inhibit'.
16a91140 144
8740c12d 145See the Emacs Lisp Reference Manual for more information.
16a91140 146
3a46642b
J
147** The colors for selected text (the region face) are taken from the GTK
148theme when Emacs is built with GTK.
149
aa1859f5
J
150** Emacs uses GTK tooltips by default if built with GTK. You can turn that
151off by customizing x-gtk-use-system-tooltips.
152
1ecb2d3f 153** Lucid menus and dialogs can display antialiased fonts if Emacs is built
3928f2b6
JD
154with Xft. To change font, use the X resource font, for example:
155Emacs.pane.menubar.font: Courier-12
99852628 156
0eb025fb 157+++
f042970d 158** Enhanced support for characters that have no glyphs in available fonts.
0eb025fb
EZ
159If a character has no glyphs in any of the available fonts, Emacs by
160default will display it either as a hexadecimal code in a box or as a
161thin 1-pixel space. In addition to these two methods, Emacs can
162display these characters as empty box, as an acronym, or not display
163them at all. To change how these characters are displayed, customize
164the variable `glyphless-char-display-control'.
165
166On character terminals these methods are used for characters that
167cannot be encoded by the `terminal-coding-system'.
168
917794d5
CY
169** On graphical displays, the mode-line no longer ends in dashes.
170
5ffb62aa 171** On Nextstep/OSX, the menu bar can be hidden by customizing
f042970d 172ns-auto-hide-menu-bar.
5ffb62aa 173
b7d65a5f
GM
174** Basic SELinux support has been added.
175This requires Emacs to be linked with libselinux at build time.
176
d8004abe
GM
177*** Emacs preserves the SELinux file context when backing up, and
178optionally when copying files. To this end, copy-file has an extra
179optional argument, and backup-buffer and friends include the SELinux
180context in their return values.
b7d65a5f
GM
181
182*** The new functions file-selinux-context and set-file-selinux-context
183get and set the SELinux context of a file.
184
a5bee597
MA
185*** Tramp offers handlers for file-selinux-context and set-file-selinux-context
186for remote machines which support SELinux.
187
a4180391
PE
188+++
189** The function format-time-string now supports the %N directive, for
190higher-resolution time stamps.
191
9c524fcb 192** The function kill-emacs is now run upon receipt of the signals SIGTERM
383ebd15 193and SIGHUP, and upon SIGINT in batch mode.
9c524fcb
GM
194
195** kill-emacs-hook is now also run in batch mode.
63c72eeb
GM
196If you have code that adds something to kill-emacs-hook, you should
197consider if it is still appropriate to add it in the noninteractive case.
9c524fcb 198
79ce172a 199** New scrolling commands `scroll-up-command' and `scroll-down-command'
0a19a6f8
JB
200(bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom
201of buffer at first key-press (instead move to top/bottom of buffer)
7b05466f 202when a new variable `scroll-error-top-bottom' is non-nil.
79ce172a 203
5a97d2da
JL
204** New scrolling commands `scroll-up-line' and `scroll-down-line'
205scroll a line instead of full screen.
206
a4b000fb 207** New property `scroll-command' should be set on a command's symbol to
b2957ea8 208define it as a scroll command affected by `scroll-preserve-screen-position'.
9013a7f8 209
d0f69533
EZ
210+++
211** If you customize `scroll-conservatively' to a value greater than 100,
212Emacs will never recenter point in the window when it scrolls due to
213cursor motion commands or commands that move point (e.f., `M-g M-g').
214Previously, you needed to use `most-positive-fixnum' as the value of
215`scroll-conservatively' to achieve the same effect.
216
217---
218** ``Aggressive'' scrolling now honors the scroll margins.
219If you customize `scroll-up-aggressively' or
220`scroll-down-aggressively' and move point off the window, Emacs now
221scrolls the window so as to avoid positioning point inside the scroll
222margin.
223
f1a5d776
CY
224** Trash changes
225
226*** `delete-by-moving-to-trash' now only affects commands that specify
227trashing. This avoids inadvertently trashing temporary files.
228
229*** Calling `delete-file' or `delete-directory' with a prefix argument
230now forces true deletion, regardless of `delete-by-moving-to-trash'.
231
f0bf7c8e
JL
232** New option `list-colors-sort' defines the color sort order
233for `list-colors-display'.
234
44198b6e
CY
235** An Emacs Lisp package manager is now included.
236This is a convenient way to download and install additional packages,
42d9cffa 237from a package repository at elpa.gnu.org.
cb6c4991
CY
238
239*** `M-x list-packages' shows a list of packages, which can be
240selected for installation.
241
242*** New command `describe-package', bound to `C-h P'.
44198b6e
CY
243
244*** By default, all installed packages are loaded and activated
245automatically when Emacs starts up. To disable this, set
246`package-enable-at-startup' to nil. To change which packages are
247loaded, customize `package-load-list'.
248
d221e780
CO
249** An Emacs Lisp testing tool is now included.
250Emacs Lisp developers can use this tool to write automated tests for
251their code. See the ERT info manual for details.
252
f065864f
CY
253** Custom Themes
254
255*** `M-x customize-themes' lists Custom themes which can be enabled.
256
782b5e8d
CY
257*** New option `custom-theme-load-path' is the load path for themes.
258Emacs no longer looks for custom themes in `load-path'. The default
259is to search in `custom-theme-directory', followed by a built-in theme
260directory named "themes/" in `data-directory'.
261
b7617f6d
CY
262*** New option `custom-safe-themes' records known-safe theme files.
263If a theme is not in this list, Emacs queries before loading it, and
264offers to save the theme to `custom-safe-themes' automatically. By
265default, all themes included in Emacs are treated as safe.
278f6845 266
4ddf410a
MA
267** The user option `remote-file-name-inhibit-cache' controls whether
268the remote file-name cache is used for read access.
269
17284e30
GM
270** The standalone programs lib-src/digest-doc and sorted-doc have been
271replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'.
272
f13183cf
CY
273** The variable `focus-follows-mouse' now always defaults to nil.

CY
301** Deletion changes
302
303*** New option `delete-active-region'.
304If non-nil, C-d, [delete], and DEL delete the region if it is active
305and no prefix argument is given. If set to `kill', these commands
306kill instead.
307
308*** New command `delete-forward-char', bound to C-d and [delete].
42d9cffa
CY
309This is meant for interactive use, and obeys `delete-active-region'.
310The command `delete-char' does not obey `delete-active-region'.
b9229673
CY
311
312*** `delete-backward-char' is now a Lisp function.
313Apart from obeying `delete-active-region', its behavior is unchanged.
314However, the byte compiler now warns if it is called from Lisp; you
315should use delete-char with a negative argument instead.
316
317*** The option `mouse-region-delete-keys' has been deleted.
318
f9d71b42
CY
319** Selection changes.
320
b1ab31ae
CY
321The default handling of clipboard and primary selections was changed
322to conform with modern X applications. In short, most commands for
323killing and yanking text now use the clipboard, while mouse commands
324use the primary selection.
325
326In the following, we provide a list of these changes, followed by a
327list of steps to get the old behavior back if you prefer that.
328
329*** `mouse-drag-copy-region' now defaults to nil.
330*** `select-active-regions' now defaults to t.
331Merely selecting text (e.g. with drag-mouse-1) no longer puts it in
332the kill-ring. The selected text is put in the primary selection, if
333the system possesses a separate primary selection facility (e.g. X).
334
335**** `select-active-regions' also accepts a new value, `only'.
336This means to only set the primary selection for temporarily active
337regions (usually made by mouse-dragging or shift-selection);
338"ordinary" active regions, such as those made with C-SPC followed by
339point motion, do not alter the primary selection.
340
341*** mouse-2 is now bound to `mouse-yank-primary'.
342This pastes from the primary selection, ignoring the kill-ring.
343Previously, mouse-2 was bound to `mouse-yank-at-click'.
344
345*** `x-select-enable-clipboard' now defaults to t on all platforms.
346*** `x-select-enable-primary' now defaults to nil.
347Thus, commands that kill text or copy it to the kill-ring (such as
348M-w, C-w, and C-k) also use the clipboard---not the primary selection.
349
350**** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now
351exactly equivalent to, respectively M-w, C-w, and C-y.
352
353**** Note that on MS-Windows, `x-select-enable-clipboard' was already
354non-nil by default, as Windows does not support the primary selection
355between applications.
356
357*** To return to the previous behavior, do the following:
358
104c2fe9 359**** Change `select-active-regions' to nil.
b1ab31ae
CY
360**** Change `mouse-drag-copy-region' to t.
361**** Change `x-select-enable-primary' to t (on X only).
362**** Change `x-select-enable-clipboard' to nil.
363**** Bind `mouse-yank-at-click' to mouse-2.
f9d71b42 364
084e6df3
JD
365*** Support for X cut buffers has been removed.
366
99f053cf
JA
367** New command `rectangle-number-lines', bound to `C-x r N', numbers
368the lines in the current rectangle. With an prefix argument, this
369prompts for a number to count from and for a format string.
370
70436396
MA
371** The command shell prompts for the shell path name, when the default
372directory is a remote file name and neither environment variable
373$ESHELL nor variable `explicit-shell-file-name' is set.

04380ff1
SM
387more variants, including Mercury, and a lot more.
388

405
817b48a7
GM
406** Directory local variables can apply to file-less buffers, in certain modes
407(eg dired, vc-dir, log-edit). For example, adding
408"(diff-mode . ((mode . whitespace)))" to your .dir-locals.el file,
409will turn on `whitespace-mode' for *vc-diff* buffers. Modes should
410call `hack-dir-local-variables-non-file-buffer' to support this.
411
6640b281
GM
412+++
413** You can prevent directory local variables from applying to subdirectories.
414Add an element (subdirs . nil) to the alist portion of any variables
415settings to indicate said section should not be applied to subdirectories.
416
8a8d54cd
VD
417** ERC changes
418
419*** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
420If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a
421successful NickServ identification, or after `erc-autojoin-delay'
422seconds. The default value, 'ident, means to autojoin immediately

488** SQL Mode enhancements.
489
9250002f
MM
490*** `sql-dialect' is a synonym for `sql-product'.
491
74790210 492*** Added ability to login with a port on MySQL and Postgres.
7492acc9 493The custom variable `sql-port' can be specified for connection to
74790210
MM
494MySQL or Postgres servers. By default, the port is not listed in
495either login parameter, but will be added to the command line if set
496to a non-zero value.
7492acc9 497
9250002f
MM
498*** Dynamic selection of product in an SQL interactive session.
499If you use `sql-product-interactive' to start an SQL interactive
500session it uses the current value of `sql-product'. Preceding the
501invocation with C-u will force it to ask for the product before
502creating the session.
503
504*** Renaming a SQL interactive buffer when it is created.
505Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres',
506`sql-mysql', etc.) with C-u will force a new interactive session to be
507started and will prompt for the new name. This will reduce the need
508for `sql-rename-buffer' is most common use cases.
509
3bd2cfef
MM
510*** Command continuation prompts in SQL interactive mode are suppressed.
511Multiple line commands in SQL interactive mode, generate command
512continuation prompts which needlessly confuse the output. These
513prompts are now filtered out from the output. This change impacts
514multiple line SQL statements entered with C-j between each line,
515statements yanked into the buffer and statements sent with
516`sql-send-*' functions.
517
7492acc9
MM
518*** Custom variables control prompting for login parameters.
519Each supported product has a custom variable `sql-*-login-params'
520which is a list of the parameters to be prompted for before a
521connection is established.
522
74790210
MM
523The lists consist of the following five tokens: `user', `password',
524`database', `server', and `port'. The order in which they appear is
525the order in which they are prompted. The tokens symbols can be
526replaced by a sublist starting with the token and followed by a plist
527which control the prompting for values. The tokens `user',
528`database', and `server' each can take a property of :default which
529specifies the value to be used if no value is entered. The
530`database', `server', and `port' tokens handle the :completion
531property which restricts the entry to either one of the values in the
532list or to one of the values returned by the function provided as the
533property value. The `database' and `server' tokens also accept the
534:file property whose value is a regexp to identify useful file names.
535
536 (user :default DEF)
537 (database :default DEF
538 :file FILEPAT
539 :completion COMPLETE)
540 (server :default DEF
541 :file FILEPAT
542 :completion COMPLETE)
543
544The FILEPAT when :file is specified is a regexp that will match valid
545file names (without the directory portion). Generally these strings
546will be of the form ".+\.SUF" where SUF is the desired file suffix.
547
548When :completion is specified, the COMPLETE corresponds to the
549PREDICATE argument to the `completing-read' function (a list of
550possible values or a function returning such a list).
5474c40f 551
30c4d8dc
MM
552*** Added `sql-connection-alist' to record login parameter values.
553An alist for recording different username, database and server
554values. If there are multiple databases that you connect to the
555parameters needed can be stored in this alist.
556
557For example, the following might be set in the user's init.el:
558
559 (setq sql-connection-alist
560 '((dev (sql-product 'sqlite)
561 (sql-database "/home/mmaug/dev.db"))
562 (prd (sql-product 'oracle)
563 (sql-user "mmaug")
564 (sql-database "iprd2a"))))
565
566This defines two connections named "dev" and "prd".
567
568*** Added `sql-connect' to use predefined connections.
569Sets the login parameters based on the values in the
570`sql-connection-alist' and start a SQL interactive session. Any
571values specified in the connection will not be prompted for.
572
573In the example above, if the user were to invoke M-x sql-connect, they
574would be prompted for the connection. The user can respond with
575either "dev" or "prd". The "dev" connection would connect to the
576SQLite database without prompting; the "prd" connection would prompt
577for the users password and then connect to the Oracle database.
578
d26b0ea9 579**** Added SQL->Start... submenu when connections are defined.
b2957ea8 580When connections have been defined, there is a submenu available that
d26b0ea9
MM
581allows the user to select one to start a SQLi session. The "Start
582SQLi Session" item moves to the "Start..." submenu when cnnections
583have been defined.
584
585**** Added "Save Connection" menu item in SQLi buffers.
586When a SQLi session is not started by a connection then
587`sql-save-connection' will gather the login params specified for the
588session and save them as a new connection.
589
74790210
MM
590*** List database objects and details.
591Once a SQL interactive session has been started, you can get a list of
592the objects in the database and see details of those objects. The
593objects shown and the details available are product specific.
594
595**** List all objects.
596Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all
597objects" will list all the objects in the database. At a minimum it
86485587 598lists the tables and views in the database. Preceding the command by
74790210
MM
599universal argument may provide additional details or extend the
600listing to include other schemas objects. The list will appear in a
601separate window in view-mode.
602
603**** List Table details.
604Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table
605details" will ask for the name of a database table or view and display
86485587 606the list of columns in the relation. Preceding the command with the
74790210
MM
607universal argument may provide additional details about each column.
608The list will appear in a separate window in view-mode.
609
7492acc9
MM
610*** Added option `sql-send-terminator'.
611When set makes sure that each command sent with `sql-send-*' commands
612are properly terminated and submitted to the SQL processor.
613
614*** Added option `sql-oracle-scan-on'.
615When set commands sent to Oracle's SQL*Plus are scanned for strings
30c4d8dc
MM
616starting with an ampersand and the user is asked for replacement text.
617In general, the SQL*Plus option SCAN should always be set OFF under
618SQL interactive mode and this option used in its place.
7492acc9
MM
619
620*** SQL interactive mode will replace tabs with spaces.
86485587 621This prevents the command interpreter for MySQL and Postgres from
7492acc9
MM
622listing object name completions when being sent text via
623`sql-send-*' functions.
624
625*** An API for manipulating SQL product definitions has been added.

856just call syntax-propertize to make sure the text is propertized.

858syntax-propertize-extend-region-functions, as well as two helper functions:
859syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords
860as-is; and syntax-propertize-rules which provides a new way to specify
861syntactic rules.

SM
863** New hook post-self-insert-hook run at the end of self-insert-command.
864

c5683ceb 866** Syntax tables support a new "comment style c" additionally to style b.
4e2db1fe 867** frame-local variables cannot be let-bound any more.
10dcc561 868** prog-mode is a new major-mode meant to be the parent of programming mode.
f44379e7
SM
869** define-minor-mode accepts a new keyword :variable.
870
b2957ea8 871** `delete-file' and `delete-directory' now accept optional arg TRASH.
f1a5d776
CY
872Trashing is performed if TRASH and `delete-by-moving-to-trash' are
873both non-nil. Interactively, TRASH defaults to t, unless a prefix
874argument is supplied (see Trash changes, above).

SM
876** buffer-substring-filters is obsoleted by filter-buffer-substring-functions.
877
00278747
SM
878** New completion style `substring'.
879
9317e499
CY
880** `facemenu-read-color' is now an alias for `read-color'.
881The command `read-color' now requires a match for a color name or RGB
882triplet, instead of signalling an error if the user provides a invalid
883input.
884
4039c786
CY
885** Tool-bars can display separators.
886Tool-bar separators are handled like menu separators in menu-bar maps,
94975270 887i.e. via menu entries of the form `(menu-item "--")'.

889** Image API
890
891*** When the image type is one of listed in `image-animated-types'
1546c559 892and the number of sub-images in the image is more than one, then the
00fe2df1
JL
893new function `create-animated-image' creates an animated image where
894sub-images are displayed successively with the duration defined by
895`image-animate-max-time' and the delay between sub-images defined
896by the Graphic Control Extension of the image.
897
1546c559
JL
898*** `image-extension-data' is renamed to `image-metadata'.

900** XML and HTML parsing
901
902*** If Emacs is compiled with libxml2 support (which is the default),
4b9832a6 903two new Emacs Lisp-level functions are defined:
84156e94
MA
904`libxml-parse-html-region' (which will parse "real world" HTML)
905and `libxml-parse-xml-region' (which parses XML). Both return an
4b9832a6
CY
906Emacs Lisp parse tree.
907
908FIXME: These should be front-ended by xml.el.

910** GnuTLS
911
912*** Emacs can be compiled with libgnutls support
913This is the default. You will then be able to use the functionality
914in gnutls.el, namely the `open-gnutls-stream' and `gnutls-negotiate'
915functions. It's easiest to use these functions through
916`open-network-stream' because it can upgrade connections through
917STARTTLS opportunistically or use plain SSL, depending on your needs.
918
919Only versions 2.8.x and higher or GnuTLS have been tested.
920
921*** gnutls-log-level
922Set `gnutls-log-level' higher than 0 to get debug output. 1 is for
923important messages, 2 is for debug data, and higher numbers are as per
924the GnuTLS logging conventions. The output is in *Messages*.

MH
926** Isearch
927
928*** New hook `isearch-update-post-hook' that runs in `isearch-update'.
929
9326ba26
CY
930** Progress reporters can now "spin".
931The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can
932now be nil, or omitted. This makes a "non-numeric" reporter. Each
933time you call `progress-reporter-update' on that progress reporter,
934with a nil or omitted VALUE argument, the reporter message is
935displayed with a "spinning bar".
936
3e214b50
JB
937** New variable `revert-buffer-in-progress-p' is true while a buffer is
938being reverted, even if the buffer has a local `revert-buffer-function'.
939
638f053a
JB
940** New variables `delayed-warnings-list' and `delayed-warnings-hook' allow
941deferring warnings until the main command loop is executed.
