Yes, that's the way Bazaar does it (bzr shell-complete), but for now this does the trick.

Also, I've been carrying around the patches from Stephen Boyd that add --dump-raw-long-options. I think it would be better if somehow 'git help' learned how to throw this output for both commands and arguments, and then use the first part for bash, or specify bash format somehow. Of course, we would need to add support for descriptions in the option parser.

It's the big world-domination plan for completions, but I haven't had time to work on that.

Cheers.
