Emacs 23.3 is primarily a bugfix release. Also included are a number of
enhancements to VC and Rmail, and a new indentation library, smie.el.
For details, see the file etc/NEWS.
${_EMACS_VERSION_MAJOR} and ${_EMACS_VERSION_MINOR} to determine installed
version of emacs.
Also, set minimum version of _EMACS_REQD to the same as
${_EMACS_VERSION_MAJOR}.${_EMACS_VERSION_MINOR}. Otherwise, buildlink
does not work for emacs lisp libraries.
Should fix PR/42763.
Patches were provided by Makoto Fujiwara in PR 43335.
Excerpt from the announcement:
In addition to a large number of bugfixes, Emacs 23.2 includes
several new packages, such as the CEDET suite of development tools
(including Semantic, a set of libraries and utilities for parsing
source code, and EDE, a package for managing code projects), and a
new mode for editing Javascript. The default mail composition mode
is now Message mode, which provides features such as MIME handling.
Many other part of Emacs have also been improved. For a more
complete list of changes, see the file etc/NEWS.
Major changes:
- Improved Unicode support.
- Font rendering with Fontconfig and Xft.
- Support for using X displays and text terminals in one session, and
for running as a daemon.
- Support for multi-file commits in distributed version-control
systems (VC-dir).
- The default X toolkit is now Gtk+, rather than Lucid.
Below is a simplified etc/NEWS; see the real file for full detail!

* Incompatible Editing Changes in Emacs 22.3

not advertised: danish-alt-postfix, esperanto-alt-postfix,
finnish-alt-postfix, german-alt-postfix, icelandic-alt-postfix,
norwegian-alt-postfix, scandinavian-alt-postfix, spanish-alt-postfix,
and swedish-alt-postfix. Use the versions without "alt-", which are
identical.

(snip)
* Changes in Emacs 22.2
** `describe-project' is renamed to `describe-gnu-project'.
** `view-todo' is renamed to `view-emacs-todo'.
** `find-name-dired' now uses -iname rather than -name
for case-insensitive filesystems.
** In Image mode, whenever the displayed image is wider and/or higher
than the window, the usual keys for moving the cursor cause the image
to be scrolled horizontally or vertically instead.
** Emacs can use stock icons in the tool bar when compiled with Gtk+.
** Scrollbars follow the system theme on Windows XP and later.
** focus-follows-mouse defaults to nil on MS Windows.
** `bad-packages-alist' will warn about external packages that are known
to cause problems in this version of Emacs.
** The values of `dired-recursive-deletes' and `dired-recursive-copies'
have been changed to `top'.
** `browse-url-emacs' loads a URL into an Emacs buffer. Handy for *.el URLs.
** The command gdba has been removed as gdb works now for those cases where it
was needed.
** desktop.el now detects conflicting uses of the desktop file.
** Compilation mode now correctly respects the value of
`compilation-scroll-output' between invocations.
** `font-lock-comment-face' no longer differs from the default on
displays with fewer than 16 colors and dark background (e.g. older
xterms and the Linux console).
* New Modes and Packages in Emacs 22.2
** bibtex-style-mode helps you write BibTeX's *.bst files.
** The new package css-mode.el provides a major mode for editing CSS files.
** The new package vera-mode.el provides a major mode for editing Vera files.
** The new package verilog-mode.el provides a major mode for editing Verilog files.
** The new package socks.el implements the SOCKS v5 protocol.
** VC
*** VC backends can provide completion of revision names.
*** VC backends can provide extra menu entries to the "Version Control" menu.
This can be used to add menu entries for backend specific functions.
*** VC has some support for Mercurial (Hg).
*** VC has some support for Monotone (Mtn).
*** VC has some support for Bazaar (Bzr).
*** VC has some support for Git.
* Incompatible Lisp Changes in Emacs 22.2
** shell.el no longer defines the aliases `dirtrack-toggle' and
`dirtrack-mode' for `shell-dirtrack-mode'.
* Lisp Changes in Emacs 22.2.
** Frame-local variables are deprecated and are slated for removal.
** The function invisible-p returns non-nil if the character
after a specified position is invisible.
** inhibit-modification-hooks is bound to t while running modification hooks.
** New function `window-full-width-p' returns t if a window is as wide
as its frame.
** The new function `image-refresh' refreshes all images associated
with a given image specification.
** The new function `combine-and-quote-strings' concatenates a list of strings
using a specified separator. If a string contains double quotes, they
are escaped in the output.
** The new function `split-string-and-unquote' performs the inverse operation to
`combine-and-quote-strings', i.e. splits a single string into a list
of strings, undoing any quoting added by `combine-and-quote-strings'.
(For some separator/string combinations, the original strings cannot
be recovered.)
Don't call pkg_info to get the installed Emacs version; always use the
version matching EMACS_TYPE set by users. Be DEPENDS to it. This should
address pkg/37146 by Aleksey Cheusov.
While here convert some emacs lisp packages to user-destdir.
