Make the new --prune-tags option work properly when git-fetch is
invoked with a <url> parameter instead of a <remote name>
parameter.
This change is split off from the introduction of --prune-tags due to
the relative complexity of munging the incoming argv, which is easier
to review as a separate change.

-Another special case of `--prune-tags` is that

-To prune tags given a URL supply the refspec explicitly:
