* Changes in Emacs 21.4
-** Under XFree86 4, the display table is modified so that `' is
-displayed as balanced quotes, not the ASCII glyphs whose shape has
-been changed generally in the XFree86 fonts.
-
** sql changes.
*** The variable `sql-product' controls the highlightng of different
default-frame-alist. It supports variable heights, like the `bar'
cursor does.
-+++
-** On X, MS Windows, and Mac OS, the blinking cursor's "off" state is
-now controlled by the variable `blink-cursor-alist'.
-
** Filesets are collections of files. You can define a fileset in
various ways, such as based on a directory tree or based on
program files that include other program files.
default, all trivial operations involving whole lines are performed
automatically. The game uses faces for better visual feedback.
++++
+** On X, MS Windows, and Mac OS, the blinking cursor's "off" state is
+now shown as a hollow box or a thin bar. However, you can control how
+it blinks off by setting the variable `blink-cursor-alist'.
+
** The new variable `x-select-request-type' controls how Emacs
requests X selection. The default value is nil, which means that
Emacs requests X selection with types COMPOUND_TEXT and UTF8_STRING,
face. This lets you have different colors or markings for vacations,
appointments, paydays or anything else using a sexp.
-+++
-** The new function `calendar-goto-day-of-year' (g D) prompts for a
-year and day number, and moves to that date. Negative day numbers
-count backward from the end of the year.
-
-** The function `simple-diary-display' now by default sets a header line.
-This can be controlled through the variables `diary-header-line-flag'
-and `diary-header-line-format'.
-
** VC Changes
*** The key C-x C-q no longer checks files in or out, it only changes
`query-replace' and related functions simply ignore
a match if part of it has a read-only property.
-** The new Lisp library fringe.el controls the apperance of fringes.
\f
* Lisp Changes in Emacs 21.4
-** `latin1-char-displayable-p' is obsoleted by `char-displayable-p'.
-
-** New coding system property `mime-text-unsuitable' indicates that
-the coding system's `mime-charset' is not suitable for MIME text
-parts, e.g. utf-16.
-
-** The argument to forward-word, backward-word, forward-to-indentation
-and backward-to-indentation is now optional, and defaults to 1.
-
+++
** The new function `window-inside-edges' returns the edges of the
actual text portion of the window, not including the scroll bar or
argument is a minibuffer. If the argument is omitted it defaults to
the current buffer.
-+++
** There is a new Warnings facility; see the functions `warn'
and `display-warning'.
** The new function `merge-coding-systems' fills in unspecified aspects
of one coding system from another coding system.
----
** The variable `safe-local-eval-forms' specifies a list of forms that
are ok to evaluate when they appear in an `eval' local variables
specification. Normally Emacs asks for confirmation before evaluating
such a form, but if the form appears in this list, no confirmation is
needed.
----
** If a function has a non-nil `safe-local-eval-function' property,
that means it is ok to evaluate some calls to that function when it
appears in an `eval' local variables specification. If the property
If the form is not "ok to call", that means Emacs asks for
confirmation as before.
-+++
** Controlling the default left and right fringe widths.
The default left and right fringe widths for all windows of a frame
of the currently defined fringe bitmaps. The width of the built-in
fringe bitmaps is 8 pixels.
-+++
** Per-window fringes settings
Windows can now have their own individual fringe widths and position
the buffer in a window, or use `set-window-buffer' to force an update
of the display margins.
-+++
** The function `set-window-buffer' now has an optional third argument
KEEP-MARGINS which will preserve the window's current margin, fringe,
and scroll-bar settings if non-nil.
write-contents-hooks to write-contents-functions.
Marked local-write-file-hooks as obsolete (use the LOCAL arg of `add-hook').
-+++
** The new variable `delete-frame-functions' replaces `delete-frame-hook'.
It was renamed to follow the naming conventions for abnormal hooks. The old
name remains available as an alias, but has been marked obsolete.
-+++
** The `read-file-name' function now takes an additional argument which
specifies a predicate which the file name read must satify. The
new variable `read-file-name-predicate' contains the predicate argument
while reading the file name from the minibuffer; the predicate in this
variable is used by read-file-name-internal to filter the completion list.
----
** The new variable `read-file-name-function' can be used by lisp code
to override the internal read-file-name function.
-+++
** The new function `read-directory-name' can be used instead of
`read-file-name' to read a directory name; when used, completion
will only show directories.
-+++
** The new function `file-remote-p' tests a file name and returns
non-nil if it specifies a remote file (one that Emacs accesses using
its own special methods and not directly through the file system).
----
** When a Lisp file uses CL functions at run-time, compiling the file
now issues warnings about these calls, unless the file performs
(require 'cl) when loaded.
-+++
+** The new Lisp library fringe.el controls the apperance of fringes.
+
** The `defmacro' form may contain declarations specifying how to
indent the macro in Lisp mode and how to debug it with Edebug. The
syntax of defmacro has been extended to
Set NAME's `edebug-form-spec' property to DEBUG. (This is
equivalent to writing a `def-edebug-spec' for the macro.
-+++
** Interactive commands can be remapped through keymaps.
This is an alternative to using defadvice or substitute-key-definition
command before remapping. It is equal to `this-command' when the
command was not remapped.
-+++
** New variable emulation-mode-map-alists.
Lisp packages using many minor mode keymaps can now maintain their own
although it applies to overlays as well. This variable was introduced
to implement the `font-lock-face' property.
-+++
** New special text property `font-lock-face'.
This property acts like the `face' property, but it is controlled by
property. Instead, it is implemented inside font-core.el, using the
new variable `char-property-alias-alist'.
-+++
** New function remove-list-of-text-properties.
The new function `remove-list-of-text-properties' is almost the same
as `remove-text-properties'. The only difference is that it takes
a list of property names as argument rather than a property list.
-+++
** New function insert-for-yank.
This function normally works like `insert' but removes the text
character of the string, the insertion of the text may be modified in
a number of ways. See the description of `yank-handler' below.
-+++
** New function insert-buffer-substring-as-yank.
This function works like `insert-buffer-substring', but removes the
text properties in the `yank-excluded-properties' list.
-+++
** New function insert-buffer-substring-no-properties.
This function is like insert-buffer-substring, but removes all
text properties from the inserted substring.
-+++
** New `yank-handler' text property may be used to control how
previously killed text on the kill-ring is reinserted.
-The value of the yank-handler property must be a list with one to four
+The value of the yank-handler property must be a list with one to five
elements with the following format:
(FUNCTION PARAM NOEXCLUDE UNDO).
called with two arguments, the start and end of the current region.
FUNCTION may set `yank-undo-function' to override the UNDO value.
-*** The functions kill-new, kill-append, and kill-region now have an
-optional argument to specify the yank-handler text property to put on
-the killed text.
+*** The functions kill-new, kill-append, and kill-region now has an
+optional third argument to specify the yank-handler text property
+to put on the killed text.
*** The function yank-pop will now use a non-nil value of the variable
`yank-undo-function' (instead of delete-region) to undo the previous
This is relevant only if Lisp code looks for
the bindings that were made with easymenu.
-+++
** The function `commandp' takes an additional optional
argument. If it is non-nil, then `commandp' checks
for a function that could be called with `call-interactively',
This is like window-height but does not count the mode line
or the header line.
-+++
** New function format-mode-line.
This returns the mode-line or header-line of the selected (or a
specified) window as a string with or without text properties.
-+++
** New functions `lax-plist-get' and `lax-plist-put'.
These functions are like `plist-get' and `plist-put' except that they
compare the property name using `equal' rather than `eq'.
-+++
** New function `tool-bar-local-item-from-menu'
The `tool-bar-add-item-from-menu' must not be used (as previously
