(find_entries): Call regex_tag_multiline after the regular parser.
(scan_separators): Check for untermintaed regexp and return NULL.
(analyse_regex, add_regex): Remove the ignore_case argument, which
is now a modifier to the regexp. All callers changed.
(add_regex): Manage the regexp modifiers.
(regex_tag_multiline): New function. Reads from filebuf.
(readline_internal): If necessary, copy the whole file into filebuf.
(readline): Skip multi-line regexps, leave them to regex_tag_multiline.
(add_regex): Better check for null regexps.
(readline): Check for regex matching null string.
(find_entries): Reorganisation.
sequences supported by gcc.
(find_entries): rewind unconditionally.
(find_entries): Do not call language functions directly, now calls
itself.
(find_entries): Do general initialisations here.
(CNL_SAVE_DEFINEDEF, C_entries, LOOP_ON_INPUT_LINES, F_getit)
(Ada_getit, Pascal_functions, Pascal_functions)

(print_help): Document it.
(main): Handle it.

inadvertently lost on 2002-04-13.
* etags.c (main): Use `sort -o TAGFILE TAGFILE' instead of
`sort TAGFILE -o TAGFILE', as POSIX 1003.1-2001 disallows
the latter usage.
inadvertently lost on 2002-04-13.
(main): Use `sort -o TAGFILE TAGFILE' instead of `sort TAGFILE -o
TAGFILE', as POSIX 1003.1-2001 disallows the latter usage.
(main): New argument -d, for specifying directory.
(usage): Document.
(get_user_id): Compute
(get_home_dir): Deleted.
(get_prefix): New function, taken from main.
(main): Check whether or not we are running setuid. Move prefix
computation to get_prefix. Don't call getpwent; we don't need to
any more. Instead, move it to get_user_id().
(process_file): Print the tags from the nodes as soon as
possible, and delete the nodes. This brings down the memory
occupancy as etags to almost the same level as when the #line
directives were not parsed.
(free_fdesc): New function.
(find_entries): Use it.
(invalidate_nodes): In etags mode, do not just mark the nodes as
invalid, do delete them.
(strcaseeq): New function.
(get_language_from_filename): Use it to do a case insenstitive
comparison if called with appropriate args.
(find_entries): Try with case insensitive match.
(process_file): Bug fixed.
the command line, in either order.
* etags.c (find_entries): Delete tags previously obtained from
file xxx.c's #line directives when parsing file xxx.y. This is
generally done for automatically generated files containing
#line directives. This handles the case when xxx.y is tagged
before xxx.c, and the entries of xxx.c pointing to xxx.y should
be discarded.
(language): Added the metasource member. Initializers changed.
(invalidate_nodes): New function.
(readline): Discard lines after having found a #line
directive pointing to an already tagged file. This handles the
case when xxx.y is tagged before xxx.c, and the entries of
xxx.c pointing to xxx.y should be discarded.
(fdesc): New structure for keeping track of input files.
(fdesc): Remove `file' member (a string) and use instead a pointer
to a file description structure.
(curfile, curfiledir, curtagfname, curlang, nocharno,
forced_lang): Global variables removed in favor of fdhead and
curfdp, pointers to file description strucures.
(longopts, main, print_help): Use the CTAGS conditional to include
or exclude options that work on etags or ctags only.
(process_file, find_entries, pfnote, add_node, put_entries,
readline): Use fdhead and curfdp.
(process_file, find_entries): Do not take an arg string, all
callers changed.
* etags.c (longopts, print_help, main): Test CTAGS to disallow
options that are not right for either etags or ctags.
* etags.c (number_len, total_size_of_entries): Define them also
in CTAGS mode, because gcc does not compile all refs away.
(MAX_DATA_LEN, MAX_SCORES): New.
(SCORE_FILE_PREFIX): If HAVE_SHARED_GAME_DIR is not defined,
default to ~/.emacs.d/games.
(get_user_id): Don't zero uid in the case where we can't get the
username.
(lose): New function.
(main): Actually use `max', and default it to MAX_SCORES.
Correctly handle new default for SCORE_FILE_PREFIX. Use `lose'
function.
(read_score): Handle the case of reading unamelen characters, then
finishing. Use mktemp if mkstemp isn't available.
(lock_file, unlock_file): Delete unused versions.
(lock_file): Always sleep, even if we unlinked the lock file.
(get_user_id): Take struct passwd as an argument.
(get_home_dir): New function.
(main): Read in user information here. Discover home directory if
necessary.
(read_score): Trim newline only in `getline' case.
(struct score_entry): Add username field.
(push_score): Use it.
(get_user_id): New function.
(main): Don't malloc excessively.
(main): Use username field.
(read_score): Read it.
(push_score): Handle it.
(write_scores) Write it.
(read_score): Handle arbitrary length data.
