up when a regexp isearch is made more general. Use symbolic
accessor functions for isearch stack frames to make usage clearer.
(search-whitespace-regexp): Made groups in documentation shy (as
is the group in the default value).
(isearch-fallback): New function, addresses problems with regexps
liberalized by `\|', adds support for liberalization by `\}' (the
general repetition construct), and incorporates behavior for
`*'/`?'.
(isearch-}-char): New command, calls `isearch-fallback' with
arguments appropriate to a typed `}'.
(isearch-*-char, isearch-|-char): Now just call `isearch-fallback'
appropriately.
(isearch-mode-map): Bind `}' to `isearch-}-char'.
(isearch-string, isearch-message,string, isearch-point,
isearch-success, isearch-forward-flag, isearch-other-end,
isearch-word, isearch-invalid-regexp, isearch-wrapped,
isearch-barrier, isearch-within-brackets,
isearch-case-fold-search):
New inline functions to read fields of a stack frame.
(speedbar-file-lists): Don't ignore file-name case on Unix and use dolist.
(speedbar-insert-files-at-point): Take an extra argument and use it to optionally find out if a subdir is empty. Also unreadable files don't get expand buttons.
(speedbar-directory-plus): New image (bitmap already existed unused).
(speedbar-expand-image-button-alist): Use it.
(Keymap Terminology): `kbd' uses same syntax as Edit Macro mode.
Give more varied examples for `kbd'.
(Creating Keymaps): Char tables have slots for all characters
without modifiers.
(Active Keymaps): `overriding-local-map' and
`overriding-terminal-local-map' also override text property and
overlay keymaps.
(Functions for Key Lookup): Mention OLP arg to `current-active-maps'.
(Scanning Keymaps): `accessible-keymaps' uses `[]' instead of `""'
to denote a prefix of no events.
`map-keymap' includes parent's bindings _recursively_.
Clarify and correct description of `where-is-internal'.
Mention BUFFER-OR-NAME arg to `describe-bindings'.
(Menu Example): For menus intended for use with the keyboard, the
menu items should be bound to characters or real function keys.
`disabled-command-hook'.
(disabled-command-hook): Keep the _variable_ as alias for
`disabled-command-function' and make obsolete.
(disabled-command-function): Function renamed from
`disabled-command-hook'. Adapt code to namechange of the variable.
