Not quite robust enough - if your superproject contains commits not
pushed upstream yet, then merge-base would still output a single
reference. This should close that gap, by requiring that the least
reachable commit be exactly the upstream origin.
gnulib-commit-check:
git submodule foreach test '$$(git rev-parse origin)' \
= '"$$(git merge-base --independent origin $$sha1)"'
