in this patch, the remote url is printed to stderr, instead of stdout,
so existing scripts should be safe.

I'm not sure if there's a command to determine the remote - I'd be
interested to know it, if there's one.

That aside, I believe this patch as an attempt at improving usability.

Compare (pre-patch):

  $ git ls-remote
  (scratch head)
  $ git-x # to determine which remote we listed refs from

with (post-patch):

  $ git ls-remote

The advantage is minor, but I feel there's some added convenience.
