It comes quite as a surprise to an unsuspecting Git user that calling
"git add submodule/file" (which is a mistake, alright) _removes_
the submodule in the index, and adds the file. Instead, complain loudly.
While at it, be nice when the user said "git add submodule/" which is
most likely the consequence of tab-completion, and stage the submodule,
instead of trying to add the contents of that directory.

Okay, so I let this slip for way too long. AFAIR I waited for
a few patches to go into 'next', and it was in an -rc cycle.
Happily, the patches seem to be in, and we're out of -rc.
Looking over the patch again, I do not find anything obviously
wrong, but certainly somebody will.
