[PATCH] Fix "git submodule status" output when "git describe" is not possible

[Alberto Bertogli <albertito@gmail.com>]

When a submodule cannot be described, doing a "git submodule status" on
the supermodule produces unnecesary and scary output, for example:

    fatal: cannot describe 'cac575f1bccf0c6942d11962cf4d44ba974d3e8e'
     cac575f1bccf0c6942d11962cf4d44ba974d3e8e megaco/megaco_tipc

Where it should just show:

     cac575f1bccf0c6942d11962cf4d44ba974d3e8e megaco/megaco_tipc

The culprit (after manual inspection of git log) seems to be commit
a2cf9f4.

This patch fixes this by making git submodule aware of that behaviour
change.
