Sorry that I forgot to answer to this. I am not sure what you mean by
"the semantics change". This patch does not change any existing
behavior. I rather see this as an extra way to specify the default
behavior of what happens on submodule update. If people do not use it
there will be no expectations broken.

Another change I am thinking of (which would definitely need an entry in
the release notes) is to change submodule foreach to iterate over all
gitmodule entries in the index/HEAD/worktree (not sure yet) instead of
"just entries that are in .git/config".

What do you think?

Cheers Heiko
