;;
+;; In addition to the ability to ignore regions that match regular
+;; expressions, Ediff can be ordered to start skipping over certain
+;; `inessential' regions. This is controlled by the variable
+;;
+;; ediff-ignore-similar-regions
+;;
+;; which, if set to t, will cause Ediff to skip over difference regions
+;; that has been found similar, i.e., where the only differences are those
+;; in the white space and newlines.
+;;
+;; Note: In order for this feature to work, auto-refining of difference
+;; regions must be on, since otherwise Ediff won't know if there are no
+;; fine differences between regions. Under X, auto-refining is a default,
+;; but it is nixed on a dumb terminal or in an Xterm window. Therefore, in
+;; a non-windowing environment, the user must explicitly turn
+;; auto-refining on (e.g., by typing `@').
+;;
+;; CAUTION: If many inessential regions appear in a row, Ediff may take a
+;; long time to jump to the next region because it has to compute fine
+;; differences of all intermediate regions.
+;;
;;
;; Highlighting difference regions
;; -------------------------------
;; faces: ediff-even/odd-diff-face-A/B. The odd and the even
;; faces are actually identical on monochrome displays, because it is
;; rather poor in what you can do on such a display. So, I chose to use
-;; italics to highlight other differences. Any ideas would be welcome. (In
-;; Lucid Emacs, the faces are different because it supports pixmaps.)
+;; italics to highlight other differences. Any ideas would be welcome.
;; There are two ways to change the default setting for highlighting faces:
;; either change the variables, as in
;;
-;; (setq ediff-current-diff-face-A (internal-get-face 'bold-italic))
+;; (setq ediff-current-diff-face-A 'bold-italic)
+;;
+;; or
+;;
+;; (setq ediff-current-diff-face-A
+;; (copy-face 'bold-italic 'ediff-current-diff-face-A))
;;
-;; (`internal-get-face' should be `get-face' if you are using Lucid Emacs)
;; or by selectively modifying the defaults:
;;
;; (add-hook 'ediff-load-hooks
;; You may also want to take a look at how the above faces are defined in
;; Ediff.
;;
+;; Note: it is not recommended to use `internal-get-face' (or `get-face' in
+;; Lucid) when defining faces for Ediff, since this may cause
+;; problems when there are several frames with different font sizes.
+;; Instead, use copy-face or set/make-face-* as shown above.
+;;
;; The last group of variables in this group,
;;
;; ediff-want-faces
;;
;; Refining difference regions
;; ---------------------------
-;; There are also variables that control the way fine differences are
-;; highlighted. This feature lets the user highlight the exact words that
+;; Ediff has variables that control the way fine differences are
+;; highlighted. This feature lets the user highlight the exact words that
;; make the difference regions in buffer A and B different. This process
;; ignores spaces, tabs, and newlines.
;;
;; diff to ignore spaces and such. Use the option '-w' for that. Diff
;; has several other useful options (type 'man diff' to find out).
;;
-;; The output from diff is found in *ediff-diff* buffer. However, this
-;; makes sense only if you also intend to use Ediff to browse through the
-;; diff'ed files before sending the patch. This is because diff.el is much
-;; faster in yielding the output of diff (Ediff is a big gun, if used
-;; for this simple purpose).
+;; The output from diff is found in *ediff-diff* buffer, which you can save.
+;; However, using Ediff for producing a diff output makes sense only if you
+;; also intend to use Ediff to browse through the diff'ed files before
+;; sending the patch. This is because diff.el, which also comes with
+;; Emacs, is much faster in yielding the output of diff (Ediff is a big
+;; gun, if used for this simple purpose).
+;;
+;; Mode line
+;; ---------
+;;
+;; When Ediff is running, the mode line of Ediff Control Panel buffer
+;; displays the current difference being displayed and the total number of
+;; difference regions in the two files.
+;;
+;; The mode line of the buffers being compared displays the type of the
+;; buffer (`A:' or `B:') and (usually) the file name. Ediff is trying to be
+;; intelligent in choosing mode line buffer identification. In particular,
+;; it works well with uniquify.el and mode-line.el packages (which improve
+;; on the default way in which Emacs displays buffer identification).
+;; If you don't like the way Ediff identifies its buffers, there is always
+;; ediff-prepare-buffer-hooks, which can be used to modify the mode line.
;;
;; Miscellaneous
;; -------------
;;
;; The total number of differences and the current difference number are
;; always displayed in the mode line of the control window.
+;;
+;; If, after making changes to buffers A and B, you decide to save them, it
+;; is recommended to use `ediff-save-buffer', which is bound to `wa' and
+;; `wb' (`wa will save buffer A and `wb' saves buffer B).
+;;
+;; Typing `wf' will also save the diff output in a file.
;;; Display Modes
;; -------------
;; Sat April 16, 1994
-;; Added Ediff to the File menu on the menu bar (version).
+;; Added Ediff to the File menu on the menu bar (FSF's version).
;; Mon April 18, 1994
;; Fixed ediff-patch-files to work with remote and compressed files.
+;; Wed July 20, 1994
+
+;; Changed menu bar items per RMS's suggestion. Changed odd/even faces
+;; in Lemacs to italic. Changed ediff-*-face-* variables so that they
+;; will contain names of faces instead of the face internal
+;; representation. (Copy-face works better with face names than with
+;; face internal representation. With face internal representation, if
+;; a face vector mentions a font explicitly, copy-face may attempt to
+;; copy this font, which would cause an error if the font has a wrong
+;; size for one of the existing frames.) Improved the way
+;; mode-line-buffer-identification is set in ediff-setup so that Ediff
+;; will accommodate the way buffers are identified in mode-line.el and
+;; uniquify.el.
+
+;; Fri August 5, 1994
+
+;; Ediff can now automatically skip over regions that differ only in
+;; the white space and line breaks. This is controled with the variable
+;; `ediff-ignore-similar-regions' and can be toggled on/off by typing
+;; `##'.
+
+;; Mon August 8, 1994
+
+;; If ediff-save-buffer is invoked with `wf', it'll save the diff
+;; output in a file.
