[PATCH] git-submodule - possibly use remote branch to describe a module

[Mark Levedahl <mlevedahl@gmail.com>]

Absent user intervention, git-submodule will maintain submodules as
headless checkouts of remote branches: such checkouts cannot be described
with reference to any local branch. So, allow describing the submodule
using remote branches before falling back on just using the commit id.
