Since 76e9bdc437 (submodule: support reading .gitmodules when it's not
in the working tree - 2018-10-25), every time you do
git grep --recurse-submodules
you are likely to see one warning line per submodule (unless all those
submodules also have submodules). On a superproject with plenty of
submodules (I've seen one with 67) this is really annoying.
The warning was there because we could not resolve extended SHA-1
syntax on a submodule. We can now. Make use of the new API and get rid
of the warning.
It would be even better if config_with_options() supports multiple
repositories too. But one step at a time.
