git-reset is yet another working tree manipulator, which should
be taught about submodules.
One use case of "git-reset" is to reset to a known good state,
and dropping commits that did not work as expected.
In that case one of the expected outcomes from a hard reset
would be to have broken submodules reset to a known good
state as well. A test for this was added in a prior patch.
