[PATCH v7 3/9] submodule: document failure to handle relative superproject origin URLs

From: Jon Seymour <jon.seymour@gmail.com>
Date: May 27, 2012, 15:34 UTC
Message-ID: <1338132851-23497-4-git-send-email-jon.seymour@gmail.com>
In-Reply-To: <1338132851-23497-1-git-send-email-jon.seymour@gmail.com>

This test case documents several cases where handling of relative superproject origin URLs doesn't produce an expected result.

submodule.{sub}.url in the superproject is incorrect in these cases:
  foo
  ./foo
  ./foo/bar

The remote.origin.url of the submodule is incorrect in the above cases
and also when the superproject origin URL is like:
  foo/bar
  ../foo
  ../foo/bar
