If you run something like "guilt header '.*'" the command would crash, because the grep comand that tries to ensure that the patch exist would detect a match, but the later code expected the match to be exact.

Fixed by comparing exact strings.

And as a creeping feature "guilt header" will now try to use the supplied patch name as an unanchored regexp if no exact match was found. If the regexp yields a unique match, it is used; if more than one patch matches, the names of all patches are listed and the command fails. (Exercise left to the reader: generalized this so that "guilt push" also accepts a unique regular expression.)
