I think the rule could be something like:

  1. If it looks like a URL ("^scheme://"), it is.

  2. Otherwise, if it is a path in the filesystem, it is.

  3. Otherwise, if it has a colon, it's host:path

  4. Otherwise, barf.

where the interesting bit is the ordering of 2 and 3.  It seems like
"git clone" follows the order above with get_repo_path. But we do not
seem to follow it in git_connect, where we prefer 3 over 2.

I don't think that is enough. Something like /path/to/foo:bar would
trigger !is_url already, but then git_connect fails.


  $ git init --bare foo:bar
  $ git clone foo:bar
  ssh: Could not resolve hostname /home/peff/foo: Name or service not known
  fatal: Could not read from remote repository.

Clone recognizes it as a path and turns it into an absolute path. It
then feeds it to the transport code, which triggers !is_url and knows to
use the git transport. But then git_connect prefers ssh over the

If you do a straight fetch, though, the transport code might see the
relative path (if you use one):

  $ git init
  $ git init --bare sub:repo
  $ git fetch sub:repo
  ssh: Could not resolve hostname sub: Name or service not known

but that still triggers the is_url above (which demands the "://").

I am not sure whether your patch covers any cases I am missing, but I
think you would need an analogous change to git_connect for these common
