* Lisp Changes in Emacs 22.1
----
-** easy-mmode-define-global-mode has been renamed to
-define-global-minor-mode. The old name remains as an alias.
+** New functions, macros, and commands
+++
-** The new function `filter-buffer-substring' extracts a buffer
+*** The new function `filter-buffer-substring' extracts a buffer
substring, passes it through a set of filter functions, and returns
the filtered substring. It is used instead of `buffer-substring' or
`delete-and-extract-region' when copying text into a user-accessible
`buffer-substring-filters' to remove soft newlines from the copied
text.
++++
+*** (while-no-input BODY...) runs BODY, but only so long as no input
+arrives. If the user types or clicks anything, BODY stops as if a
+quit had occurred. while-no-input returns the value of BODY, if BODY
+finishes. It returns nil if BODY was aborted.
+
++++
+*** New function `looking-back' checks whether a regular expression matches
+the text before point. Specifying the LIMIT argument bounds how far
+back the match can start; this is a way to keep it from taking too long.
+
++++
+*** New functions `make-progress-reporter', `progress-reporter-update',
+`progress-reporter-force-update', `progress-reporter-done', and
+`dotimes-with-progress-reporter' provide a simple and efficient way for
+a command to present progress messages for the user.
+
++++
+*** The new primitive `get-internal-run-time' returns the processor
+run time used by Emacs since start-up.
+
++++
+*** The new function `called-interactively-p' does what many people
+have mistakenly believed `interactive-p' did: it returns t if the
+calling function was called through `call-interactively'. This should
+only be used when you cannot add a new "interactive" argument to the
+command.
+
++++
+*** The new function `assoc-string' replaces `assoc-ignore-case' and
+`assoc-ignore-representation', which are still available, but have
+been declared obsolete.
+
+---
+*** New function quail-find-key returns a list of keys to type in the
+current input method to input a character.
+
++++
+*** New functions posn-at-point and posn-at-x-y return
+click-event-style position information for a given visible buffer
+position or for a given window pixel coordinate.
+
++++
+*** The new primitive `set-file-times' sets a file's access and
+modification times. Magic file name handlers can handle this
+operation.
+
++++
+*** The new function syntax-after returns the syntax code
+of the character after a specified buffer position, taking account
+of text properties as well as the character code.
+
+*** `syntax-class' extracts the class of a syntax code (as returned
+by syntax-after).
+
++++
+*** New function `line-number-at-pos' returns line number of current
+line in current buffer, or if optional buffer position is given, line
+number of corresponding line in current buffer.
+
++++
+*** New function `macroexpand-all' expands all macros in a form.
+It is similar to the Common-Lisp function of the same name.
+One difference is that it guarantees to return the original argument
+if no expansion is done, which may be tested using `eq'.
+
++++
+*** New macro with-local-quit temporarily sets inhibit-quit to nil for use
+around potentially blocking or long-running code in timers
+and post-command-hooks.
+
+---
+** easy-mmode-define-global-mode has been renamed to
+define-global-minor-mode. The old name remains as an alias.

** An element of buffer-undo-list can now have the form (apply FUNNAME
. ARGS), where FUNNAME is a symbol other than t or nil. That stands
clickable link with the new function `mouse-on-link-p'. This is the
function used by the new `mouse-1-click-follows-link' functionality.

-arrives. If the user types or clicks anything, BODY stops as if a
-quit had occurred. while-no-input returns the value of BODY, if BODY
-finishes. It returns nil if BODY was aborted.
-
+++
** `set-auto-mode' now gives the interpreter magic line (if present)
precedence over the file name. Likewise an <?xml or <!DOCTYPE declaration
will give the buffer XML or SGML mode, based on the new var
`magic-mode-alist'.

-the text before point. Specifying the LIMIT argument bounds how far
-back the match can start; this is a way to keep it from taking too long.

** To manipulate the File menu using easy-menu, you must specify the
proper name "file". In previous Emacs versions, you had to specify
** set-buffer-file-coding-system now takes an additional argument,
NOMODIFY. If it is non-nil, it means don't mark the buffer modified.

-of the character after a specified buffer position, taking account
-of text properties as well as the character code.

** An interactive specification may now use the code letter 'U' to get
the up-event that was discarded in case the last key sequence read for a
undo-outer-limit, garbage collection empties it. This is to prevent
it from using up the available memory and choking Emacs.

-** New functions posn-at-point and posn-at-x-y return
-click-event-style position information for a given visible buffer
-position or for a given window pixel coordinate.
-
+++
** skip-chars-forward and skip-chars-backward now handle
character classes such as [:alpha:], along with individual characters
+++
** The function `eql' is now available without requiring the CL package.
-+++
-** The new primitive `set-file-times' sets a file's access and
-modification times. Magic file name handlers can handle this
-operation.

+++
** The display space :width and :align-to text properties are now
supported on text terminals.
position. The cursor may now be placed on any character of such
strings by giving that character a non-nil `cursor' text property.

-** New macro with-local-quit temporarily sets inhibit-quit to nil for use
-around potentially blocking or long-running code in timers
-and post-command-hooks.
-
** The first face specification element in a defface can specify
`default' instead of frame classification. Then its attributes act as
defaults that apply to all the subsequent cases (and may be overridden
If either property is not set, the default `overlay-arrow-string' or
'overlay-arrow-fringe-bitmap' will be used.
-+++
-** New function `line-number-at-pos' returns line number of current
-line in current buffer, or if optional buffer position is given, line
-number of corresponding line in current buffer.
-
+++
** The default value of `sentence-end' is now defined using the new
variable `sentence-end-without-space' which contains such characters
`format' are now documented. Some flags that were accepted but not
implemented (such as "*") are no longer accepted.

-** New function `macroexpand-all' expands all macros in a form.

-One difference is that it guarantees to return the original argument

** New function `delete-dups' destructively removes `equal' duplicates
from a list. Of several `equal' occurrences of an element in the list,
