I thought about this too.  I was trying to imaging what kind of
structure one would need to describe the version control completer.
One would intuitively build something like

vc_commands = ['info','update', 'bundle', ...]
vc_subcommands = {'bundle' : ['--output','-r'], ...}
vc_subcommand_expand = {'--output': file_complete,
		        '-r': revision_complete,
			...}

def revision_complete(self, input):
    rev_re = re.compile('...')
    cur_rev = rev_re.match(commands.getoutput('bzr log -r -1')...)
    
    return ['BASE',cur_rev,'TIP',...]


On the other hand, how do we keep such structures up to date?  It
would be ideal if the program itself could provide a clue to its
completion.

I think these structures already exist in bzr and hg.  In fact,
looking in the directory tree, I think we are looking for

bzrlib/shellcomplete.py

I'll grab the latest copy of bzr and play around.
