Nice code size reduction.

You could consolidate the two dictionaries like this, to avoid making
the same choice twice and make the code more pleasant to read:

  (build, outstr) = { 1: (__build_cover, 'the cover message'), 4:
(__build_message, 'patch "%s"' % args[0]) }

Hmm. I must say I find all the args[x] a bit hard to read. I'd prefer
symbolic names.
