Maybe worth reporting to the git list as an enhancement request to 'git
grep' to search the textual representation of submodules?  At any rate,
'git log -p gnulib' will show you that commit id.

You don't even have to make a commit.  It is sufficient to do:

cd coreutils
git syncsub
git add gnulib
./bootstrap && ./configure && make check

and, if the results are to your liking, finally do the 'git commit'.
