Yes. If I read the code correctly the submodule is cd'ed in before
the foreach command is executed, so $sm_path should only be used for
displaying info about where the command is executed anyway. Looks
like your code is doing the right thing adjusting $sm_path to be
relative to the directory the user is in. But a test showing that
would really be nice ;-)

Sorry, I should have been more specific here. I saw that you did some
changes to make "submodule add" do the right thing with relative paths,
but the following change to t7406 does not work like I believe it
should but instead makes the test fail:

I meant that both commands still print the submodule names from the
top-level directory, not the one the user is in.
