I'm going to blame my poor commit msg for this.
Essentially it would be nice if when a user explicitly says "I want to
init submodule b" that we obey and do just that. What this patch does
is allow for a user to do that and the "submodule.<name>.active" config
option will only be set to 'true' in the event that that the submodule
isn't already marked as being active/interesting by some other means.
So if we did
git clone --submodule-spec=lib/
then each module under 'lib/' won't have their submodule.<name>.active
config set since submodule.active=lib/ already encompasses them.
But if no submodule-spec was given then it would default to all
submodules and set every submodule's submodule.<name>.active config to
true.
I'll add a few tests to illustrate this.
