(imenu--generic-function): Avoid mapcar.
(imenu--replace-spaces): Function removed.
(imenu--completion-buffer): Use subst-char-in-string.
(imenu-add-to-menubar): Use keymap inheritance.
(MAX_MAP_SET_LEVEL): Increased to 30.
(PUSH_MAPPING_STACK): Enclose with do-while block.
(POP_MAPPING_STACK): Likewise.
(stack_idx_of_map_multiple): New variable.
(CCL_CALL_FOR_MAP_INSTRUCTION): New macro.
(ccl_driver) <CCL_IterateMultipleMap>: If the content is a symbol,
call the corresponding CCL program by
CCL_CALL_FOR_MAP_INSTRUCTION.
(ccl_driver) <CCL_MapSingle>: Likewise.
(ccl_driver) <CCL_MapMultiple>: Rewritten to fix many bugs, deal
with the case where looking up process reaches to the end of
map-set, and call CCL programs as the above change.
(quail-show-keyboard-layout): Docstring modified.
(quail-select-current): Likewise.
(quail-build-decode-map): Change arg MAP to MAP-LIST to avoid
infinite recursive call.
(quail-help): Check quail-translation-docstring. Format of the
output changed.
(quail-help-insert-keymap-description): Adjusted for the above
change.
non-unified diffs. Some functionality moved into `diff-hunk-text' and
`diff-find-text'. Add OTHER-FILE, DRY-RUN, POPUP, and NOERROR
arguments. If DRY-RUN is true, don't actually modify anything. Only
reposition point in the patched file if the patch succeeds. Only pop
up another window if POPUP is true. Emit a message describing what
happened if successful, and at what line-offset. Automatically detect
reversed hunks and do something appropriate.
(diff-hunk-text, diff-find-text): New functions.
(diff-filter-lines): Function removed.
(diff-test-hunk): New function.
(diff-goto-source): Rewritten in terms of diff-apply-hunk.
read-only in a dumped Emacs.
(mmap_fd_1): New variable.
(mmap_set_vars): Remove local `fd'. Save mmap_fd in mmap_fd_1,
restore it from there.
(r_alloc, r_re_alloc, r_alloc_free): Call r_alloc_init
unconditionally so that mmap_fd can be initialized there.
(r_alloc_init_fd): Open-coded in r_alloc_init; function removed.
(r_alloc_init) [REL_ALLOC_MMAP && !MAP_ANON]: Open /dev/zero.
(r_alloc_init) [REL_ALLOC_MMAP && MAP_ANON]: Set mmap_fd to -1.
