Looking good to me. Please add tests for "diff.ignoreSubmodules"
and "submodule.<name>.ignore", the latter both in .gitmodules and
.git/config. While doing some testing for this thread I found an
inconsistency in git show which currently honors the submodule
specific option only from .git/config and ignores it in the
.gitmodules file (depending on the outcome of the discussion on
what '--ignore-submodules=all' should ignore we might have to fix
that one afterwards).
I'd suggest to also add the --ignore-submodules option in another
patch on top, because the user should be able to override the
configuration either way. And what about having the '-f' option
imply '--ignore-submodules=none'?
