I think the commit message should add some details about how the patch
changes the completion script's behavior.  At least I didn't know
offhand what "DWIM mode for git checkout" is, and once I found it
(70c9ac2 (DWIM "git checkout frotz" to "git checkout -b frotz
origin/frotz", 2009-10-18), right?), I didn't know how the completion
script is supposed to support that, and once I applied the patch and
played around a bit, I was surprised that only 'git checkout h<tab>'
includes the 'html' branch but 'git checkout <tab>' don't.

You could use the __git_find_on_cmdline() helper function instead.
