Changes to support ChangeLog.10+.
(main): Tidy up usage string. Fix "Use of uninitialized value" warning. Set version to 0.2. Parse the directory listing to get any ChangeLog.n file, not just 1..9. (header_match_p, entry_match_p, print_log, parse_changelog): Remove Perl prototypes (their purpose is to help the parser, which isn't needed here, not declare arguments). (parse_changelog): Make --reverse faster on big batches by not modifying the entries list.
