(no_line_directive): New global var; set it for old behaviour.
(main): Remove some #ifdef in the getopt switch.
(add_node, put_entries): Code added to merge different chunks of
nodes referring to the same file. Currently the tags are just
appended, without any check for duplicates.
(Perl_functions): Do not special case ctags.
(readline): Identify #line directives and do the right thing.
(nocharno, invalidcharno): New global vars.
(process_file): Reset nocharno.
(readline): Set nocharno.
(pfnote): Read nocharno and maybe put invalidcharno in node.
(total_size_of_entries, put_entries): Use invalidcharno.
* etags.c: Keep the whole tag table in memory, even in etags mode.
(main): Call put_entries here even in CTAGS mode.
(main, process_file): Check the return values of fclose and pclose.
(process_file): Do not call put_entries after parsing each file.
(process_file): Canonicalise file names even for ctags.
(process_file): Set curfile here...
(find_entries): ... not here any more.
(add_node): In etags mode, build a linked list of entries (on
right pointer) for each file, and link the first entry of each
file on left nodes.
(put_entries): Print here the name of the file.
(put_entries): Print the entries starting from the first file.
(number_len, total_size_of_entries): Define these only iin etags
mode, make the second work only on the right nodes.
* etags.c: Make all global variables static.
* ediff-hook.el: Got rid of autoloads. Not needed, since the hook
is loaded.
* ediff-mult.el (ediff-intersect-directories,
ediff-prepare-meta-buffer,ediff-get-directory-files-under-revision):
cleanup.
(ediff-draw-dir-diffs): now supports the "C" command in directory
difference buffer.
(ediff-dir-diff-copy-file): new function that implements copying
of files from one Ediff dir to another
(ediff-bury-dir-diffs-buffer): kills the buffer instead.
(ediff-append-custom-diff): better error msgs.
* ediff-util.el (ediff-compute-custom-diffs-maybe): buglet fix.
(ediff-inferior-compare-regions): Use
ediff-clone-buffer-for-region-comparison. Better and simpler interface.
* ediff.el (ediff-directories-internal): Cleanup.
(ediff-clone-buffer-for-region-comparison): Better interface.
(mode-line, tool-bar, minibuffer-prompt, region, fringe, bold, italic)
(bold-italic, underline, highlight, secondary-selection, fixed-pitch)
(variable-pitch, trailing-whitespace): Don't use the old-style entries.
(mode-line-inactive, header-line): Move the `t' section to the
beginning so the `:inherit' setting can be shared.
(sgml-start-tag-regex, sgml-font-lock-keywords-1, sgml-mode-common)
(sgml-tags-invisible, sgml-beginning-of-tag):
Allow _ : and non-ASCII in tag names, as required for XML.
(sgml-name-char): Don't assume anything about charsets handled by encode-char.
