[PATCH 2/2] [WIP] Allow running git init on a remote repository specification.

[Peter Krefting <peter@softwolves.pp.se>]

If we pass a remote repository specification to git init, we should try
connecting to the remote and run git init there. Not all transports
can support this, so fall back to reporting an error message for those
that cannot.

This one doesn't work. I am not sure getting this to work is even possible.

  $ ~/proj/git/git-init remote.server:/home/peter/foobartest.git
  bash: git-init: command not found
  error: cannot run ssh: No such file or directory

(it is the remote side that complains about not finding "git-init")
