Re: [PATCH 4/7] Allow programs to not depend on remotes having urls

> For fetch and ls-remote, which use the first url of a remote, have
> transport_get() determine this by passing a remote and passing NULL
> for the url. For push, which uses every url of a remote, use each url
> in turn if there are any, and use NULL if there are none.
>
> This will allow the transport code to do something different if the
> location is not specified with a url.
>
> Also, have the message for a fetch say "foreign" if there is no url.
