PATCH: _git space pollution

[Clint Adams <clint@xxxxxxx>]

This parameter is used exactly twice, immediately after its assignment.
I would say that all the globally-declared parameters should be prefixed
with _git to avoid namespace pollution, but really they shouldn't be in
the global space at all.
