Same here.

Unfortunately you'll get another two "fatal: Not a git repository:" errors
when you drop this. Further down a "git rev-list" and a "git log" are run
on the submodule unless one of the "missing" variables is set. But this
doesn't feel quite right as we are misusing the missing_src variable for
something else here ...

I agree that this is much better than just piping all errors to /dev/null,
but I was thinking of
+ test $status != D &&
instead of
+ test -e "$name/.git" &&
above to still catch errors where the submodule repo is gone but the
submodule wasn't deleted.
The following diff silences all "fatal: Not a git repository:" errors for
me using the status variable. But now four tests in t7401 are failing
because they disagree about an empty line and/or the "(0)" at the end of
a line. But this could be a good starting point (and includes a test for
what we are trying to fix here :-).
