Sure, but a submodule is checked out "at a commit", so if two branches
of history are merged, and they conflict over which place the
submodule is at.... shouldn't that produce a conflict??

I mean, how is the merge algorithm supposed to know which is right?
The patch you linked appears to be able to resolve it to the one which
contains both commits.. but that may not actually be true since you
can rewind submodules since they're *pointers* to commits, not commits
themselves.

I'm not against that as a possible strategy to merge submodules, but
it seems like not necessarily something you would always want...

Thanks,
Jake
