possibly, but more likely the user would have identified which is the best
remote to use to find her missing sha1.

I was presuming a reverse time sequence, where the user had already set up
the desired remote, but hadn't managed to change the URL in .gitmodules; but
either way, the user then let's 'git submodule' do the hard work of fetching
the correct sha1 to checkout.

I didn't think that there was a command yet to do the URL update, which
would most likely match one of the sub-module's URLs.
