This commit adds support for POSIX extended regular expressions and fixes a long-standing memory leak (pattern buffer was never freed). It also implements a new interface function to read exclude patterns from a FILE, which passes an additional parameter to its callback function, thereby allowing to preserve its state between invocations. * lib/exclude.c (struct patopts): Pack regex and pattern into union. (pattern_buffer): New struct. (exclude): New member patbuf. (exclude_add_pattern_buffer): New function. (free_exclude_segment): Free regexps. (free_exclude): Free allocated pattern buffers. (exclude_patopts): New function. (file_pattern_matches): Use exclude_patopts. (add_exclude): support regexps. (add_exclude_fp): New function. (add_exclude_file): Rewrite using add_exclude_fp. (fnmatch_pattern_has_wildcards): Support posix extended regexps. * lib/exclude.h (EXCLUDE_REGEX, EXCLUDE_ALLOC): New flags. (add_exclude_fp) (exclude_add_pattern_buffer): New prototypes. * modules/exclude: Depends on regex and filename.
