Well, now I actually looked at it, and it was pretty easy after all.
The changes below seem to enable support for both ignore setting in
.gitmodules, and also --ignore-submodules switch, for git add, on top
of my patch for commit.

So I'm going to do some more testing, write tests for git add with
ignoring submodules the various ways, and then post two patches
rearranged, one for git add, and second for git commit on top of that,
as you guys suggested. Including the change suggested by Jens, to not
mess with index_differs_from() in diff-lib.c, that works fine too.
