Gnus support code, and use special article copy buffer
`(gnus-original-article-buffer)' instead. This allows to get rid
of article-hide-headers usage (which breaks in the latest Gnus
version). Thanks to Detlev Zundel.
(PTR_TO_OFFSET, POS_AS_IN_BUFFER): Move to a better place.
(ISDIGIT, ISCNTRL, ISXDIGIT) [!emacs]: Remove duplicate definition.
(regex_compile): Use RE_FRUGAL instead of RE_ALL_GREEDY.
(re_compile_pattern): Use size_t for length.
(init_syntax_once): Move to a better place.
* regex.h: Merge changes from GNU libc. Indent cpp directives.
(RE_FRUGAL): Replaces RE_ALL_GREEDY (inverted meaning).
(KEYMAPP): New macro.
(Fkeymap_parent, Fset_keymap_parent): Use it.
(fix_submap_inheritance): Mark it static.
(define_as_prefix, describe_buffer_bindings, describe_command)
(describe_translation, describe_map): Complete prototypes.
Add support for :inherit attribute.
Add support for relative face heights.
(custom-face-attributes-get):
Treat `nil' as being a default value for :inherit (as well as `unspecified').
Update doc string.
(face-attribute-name-alist):
Add :inherit.
(face-valid-attribute-values):
Handle :inherit.
(face-read-string):
Rephrase prompt to be less confusing.
Assume that DEFAULT is a string, since we must return a string.
(face-read-integer):
Use `format' to turn DEFAULT into an acceptable default for face-read-string.
Match NEW-VALUE against the string "unspecified", not the symbol
`unspecified', since that's what face-read-string returns.
(read-face-attribute):
Lookup a name for old-value in valid, and use it as a default if we find one.
Treat all values from face-read-string as strings.
If the default is used, don't do any more processing on the value,
just use the old value directly.
(read-face-and-attribute, modify-face):
Tweak prompt.
(read-face-name):
Don't assume prompt ends with a space.
