I see the function in git-submodule.sh was named kind of reverse. How
about we do it more naturally here and call this 'rev-name' instead?
That makes is more clear to me and is also similar to the used variable
name 'revname'.

I would also prefix it differently like 'get' or 'calculate' instead of
'print' since it tries to find a name and is not just a simple lookup.

So in summary I would prefer something like 'get-rev-name' as a name for
the subcommand here.
