Look for cased character classes when deciding on case-fold-search, #'isearch
lisp/ChangeLog addition:
2015-03-11 Aidan Kehoe <kehoea@parhasard.net>
* isearch-mode.el:
* isearch-mode.el (isearch-fix-case):
Use the new #'no-case-regexp-p function if treating ISEARCH-STRING
as a regular expression; otherwise, use the [[:upper:]] character
class.
* isearch-mode.el (isearch-no-upper-case-p): Removed.
* isearch-mode.el (with-caps-disable-folding): Removed.
These two haven't been used since 1998.
* occur.el (occur-1):
Use #'no-case-regexp-p here.
* replace.el (perform-replace):
Don't use #'no-upper-case-p, use #'no-case-regexp-p or
(string-match "[[:upper:]]" ...) as appropriate.
* simple.el:
* simple.el (no-upper-case-p): Removed. This did two different
things, and its secondary function (examining regular expressions)
just became much more complicated; move the regular expression
functionality to its own function, use character classes when
examining non-regular-expressions instead.
The code to look for character classes, and the design decision
that this should be done, are from GNU, thank you Stefan Monnier.
* simple.el (no-case-regexp-p): New.
Given a REGEXP, return non-nil if it has nothing to suggest an
interactive user wants a case-sensitive search.
* simple.el (with-search-caps-disable-folding):
* simple.el (with-interactive-search-caps-disable-folding):
Update both these macros to use #'no-case-regexp-p.

@node Reading Mail, Calendar/Diary, Sending Mail, Top @chapter Reading Mail @cindex mail @cindex message XEmacs provides several mail-reading packages. Each one comes with its own manual, which is included in each package. The recommended mail-reading package for new users is VM. VM works with standard Unix-mail-format folders and was designed as a replacement for the older Rmail. XEmacs also provides a sophisticated and comfortable front-end to the MH mail-processing system, called @samp{MH-E}. Unlike in other mail programs, folders in MH are stored as file-system directories, with each message occupying one (numbered) file. This facilitates working with mail using shell commands, and many other features of MH are also designed to integrate well with the shell and with shell scripts. Keep in mind, however, that in order to use MH-E you must have the MH mail-processing system installed on your computer. The @dfn{Everything including the kitchen sink} package @samp{Gnus} is also available as an XEmacs package. Gnus also handles Usenet articles as well as mail. @samp{MEW} (Messaging in the Emacs World) is another mail-reading package available for XEmacs. Finally, XEmacs provides the Rmail package. Rmail is (currently) the only mail reading package distributed with FSF GNU Emacs, and is powerful in its own right. However, it stores mail folders in a special format called @samp{Babyl}, that is incompatible with all other frequently-used mail programs. A utility program is provided for converting Babyl folders to standard Unix-mail format; however, unless you already have mail in Babyl-format folders, you should consider using Gnus, VM, or MH-E instead.
