Teach 'git remote' how to cleanup stale tracking branches.

Browse Source

which were removed by the remote system, 'git remote prune <n>'
can now be used to delete any tracking branches under <n> which
are no longer available on the remote system.

The remote configuration is achieved using the `remote.origin.url` and
`remote.origin.fetch` configuration variables. (See
gitlink:git-config[1]).
