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.

This directory contains C header files containing machine-specific
definitions.  Each file describes a particular machine.  The emacs
configuration script edits ../config.h to include the appropriate one of
these files, and then each emacs source file includes config.h.

template.h is a generic template for machine descriptions; it
describes the parameters a machine file can specify.


General XEmacs Changes
----------------------
1. Removed all code dealing with VALBITS and XSET*.  These are handled
   differently in XEmacs.

2. Removed all defines of WORDS_BIGENDIAN.  Now determined by configure.

3. Put #ifndef PURESIZE around all PURESIZE defines so that it can be
   overridden at configure time.

4. Removed all defines of NO_ARG_ARRAY.  The arg-array hack is not
   done in XEmacs. (If you want to put it back, use configure --
   autoconf has a check for this.)

5. Removed all defines of BITS_PER_INT, BITS_PER_LONG -- now
   determined by configure.

See ../s/README for a list of other changes made to the FSF 19.30
configuration files for XEmacs.
