+cc Jacob and Lars who work with submodules as well.

So you roughly do
git checkout -b new-topic
# change the submodule to point at the latest upstream version:
git submodule update --remote <submodule-path>
git commit -a -m "update submodule"
git checkout master
git merge new-topic

git -C <submodule-path> commit
should trigger a commit in the superproject as well, that changes the gitmodules
file? What do you record in the git modules file that needs updating?
As the version is tracked via the gitlink entry, I do not see the

So you are proposing to put the revision into the gitmodules file?
That would be redundant with the actual gitlink entry in your tree.
(as shown via `git submodule status`)
What would happen if the recorded revision in the gitmodules file and the
gitlink are out of sync?
Oh, are you just proposing to actually make `git checkout` aware of the
submodules? See. I would welcome such a change and be happy th
which has some attempts for checkout including the submodules.
I also tried writing some patches which integrate checking out submodules
via checkout as well. A quicker `solution` would be a config option that
just runs `git submodule update` after each checkout/pull etc.

See config options diff.submodule and status.submoduleSummary.
