Hmph. Can we then make "--recurse-submodules" an obsolete way to
spell "--submodule-spec ."? I am not actively suggesting to
deprecate it; I am trying to see if there are semantic differences
between the two.
I am also wondering "--recurse-submodules=<pathspec>" would be a
better UI, instead of introducing yet another option.

With reflowing it is unnecessarily harder to spot what got changed.
"and clone" is inserted, "--init" and "--recursive" were swapped.
Any other changes?

Hmph, doesn't OPT_STRING_LIST work for this thing?

OK. Each pathspec becomes submodule.active in the newly created
repository.
