I think you're right that it's not a good fit for grep, but maybe for
some other commands.  mv and commit come to mind.  I'll look into this
as I'm trying to add completions for the more common (i.e. ones that I
use) porcelain commands.

This updated patch removes the __git_has_doublehash line.  However, I
just noticed that d773c631 added __git_has_doublehash to prevent
completions of long options after --.  So, maybe it's not too
redundant and my first patch might be better.
