[PATCH] submodule-config: Untangle logic in parse_config
This improves readability of the parse_config logic by making it more concise.

Eric commented on this during the long series for parallelizing
fetching submodules. I realized this can be added as an independant patch
as it doesn't interfere with the series at all, but rather was needed for the
next series I planned to put on top (parallelize git submodule). I need to
rethink the next series anyway, so I extracted this patch as a useful
readability improvement.
