Ok so this function here reads a recurse submodules parameter which is
a boolean or it can be set to the word "checkout"? Why does checkout
need its own value separate from true? Just so that we have a synonym?
or so that we can expand on it in the future?

I think eventually we want all the commands that touch the worktree to
be able to cope with submodules.

  Now what should e.g. git-revert --recurse-submodules do?
  yes == "checkout" means we'd revert the superproject commit and
  if that commit changed any submodule pointers we'd just "checkout"
  those states in the submodule.

  For revert you could also imagine to have
  git-revert --recurse-submodules=revert-in-subs
  that would not repoint the submodule pointer to the old state, but
  would try to revert $OLD..$NEW in the submodule and take the newly
  reverted state as the new submodule pointer.

As I want to focus on checkout first, I went with "yes == checkout"
here (or rather the other way round).
