The style used in the other script might be more modern, but given
that the existing one (in the post context) uses the same older
style, I think that would be OK.

I do not like this part.  The "rm -f" we saw in the "fetch --all" test
was "make sure it is missing, so that we can be sure that presence
after running 'git fetch' *is* a bug".  But using $fh later ...

... like this means now we depend on FETCH_HEAD being in all
submodule repositories before we start this step.

I think we should instead enumerate submodule repositories, instead
of enumerating existing .git/FETCH_HEAD files.
