[PATCH v4 02/12] Allow programs to not depend on remotes having urls

From: Daniel Barkalow <barkalow@iabervon.org>

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.
