I understand.

I do. I just feel a bit disturbed each time ;-)

I agree it's less pleasing, may be I wrote too many parsers that
blew up in my face on such ambiguities, but we use a scanner
(optparse) to analyze the options and I don't think it will be
easy to take that into account. Even if this second form
describes what we will really accept or not: 'bzr emit
PUBLIC_BRANCH' is illegal.
