* etags.c: Honour #line directives.
(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.
