$from_id, $to_id variables should be local per PATCH. Fix error in git_patchset_body for file creation (deletion) patches, where instead of /dev/null as from-file (to-file) diff header line, it had link to previous file with current file name. This error occured only if there was another patch before file creation (deletion) patch. Signed-off-by: Jakub Narebski <jnareb@gmail.com> Signed-off-by: Junio C Hamano <junkio@cox.net>
