Hi,

We differentiate between _git_whatever() and __git_whatever()
functions. The former performs completion for the 'whatever' git
command/alias, the latter is a completion helper function. This
is a helper function, so it should begin with double underscores.

A while ago the completion script was made 'set -u'-clean. (If 'set
-u' is enabled, then it's an error to access undefined variables).
I'm not sure how many people are out there who'd use this script for
tcsh while having 'set -u' in their profile... probably not that
many. Still, I think it would be great to keep it up.
Here $2 would be undefined, so accessingit it would cause an error
under those semantincs. Please use ${2-} instead (use empty string
when undefined).

Same here.

And here.
Thanks
