Probably, yes.

I think the code in transport-helper should be prepared to deal with
such a field appropriately, since it knows beforehand that only a few
operations will be performed on such a remote (I'm guessing just the
'list' command).

Let's not duplicate that logic, if git can figure out where we are, it
should do so, if it can't, then the helper can't either.

Probably the above, if there is going to be a git repository, we'll
have found it, if there isn't one, we're in 'bare' mode.
