archive: specfile support (--pretty=format: in archive files)
Add support for a new attribute, specfile. Files marked as being specfiles are expanded by git-archive when they are written to an archive. It has no effect on worktree files. The same placeholders as those for the option --pretty=format: of git-log et al. can be used. The attribute is useful for creating auto-updating specfiles. It is limited by the underlying function format_commit_message(), though. E.g. currently there is no placeholder for git-describe like output, and expanded specfiles can't contain NUL bytes. That can be fixed in format_commit_message() later and will then benefit users of git-log, too.
