  Well given that we now use submodules at work, and that git is
nowadays somewhere in the top 5 of my most consciously (as opposed to
the compiler that I rarely call by hand) used software suites (among my
editor, my MUA, my shell and my tiling WM), I'm very much interested in
tackling some things about what is (not) done with submodules yet.

  I sent a mail some time ago about those issues, in short words, those
concern git-checkout, git-reset, git-fetch and git-push for starters.
I'm not sure I can help with the code a lot, but I can for sure provide
a comprehensive list of things I would like the porcelain to do with
submodules if that helps.

  You mean the git checkout issue ? Because the issue is twofold, one
there is the missing warnings that users can shoot themselves in the
foot unnoticed, and there is the fact that "git checkout -- $foo" does
not what it should when "$foo" is a valid revision (and *that* is a
really really bad bug, that if I'm correct changing parse_options flags
to KEEP_DASHDASH fixes alright).
