Ok, now this makes sense. "git commit" strips off the diff added by
-v by skipping everything starting with "\ndiff --git ". But that
logic fails when the "diff.submodule = log" setting adds a shortlog
instead of a regular diff, as that starts with "\nSubmodule ".

The diff below fixes the problem you describe for me. (But I do not
consider it a worthwhile fix in its current form because a line
starting with "Submodule " might appear in a perfectly normal commit
message, while "diff --git " most probably won't).

And while testing this issue I noticed another problem: When using
"git commit -a" not only the staged commits of a submodule get
committed, but also the unstaged commits. Will look into that too.
