Make life easier for callers of RunGitCmd()
Make life easier for callers of RunGitCmd()

Mixing the stdout/stderr streams from our call to git is the default; we shouldn't require callers to deal with a separate stderr stream when the default makes it such that it will _ALWAYS_ be empty... so only provide that to the caller if they specifically requested it (and, in all our use cases of it, no one does right now).
