Aah, you must be looking at submodule.c from current master. Then you'll
find is_submodule_modified() at that location, where of course the -1 is
needed for cp.out because later read() and close() are used on it.

But I was trying to fix a problem introduced by 496b35e7 in current next,
where the new function fetch_populated_submodules() is located there. And
in that function the output is not read and so cp.out = 0 is the right
thing to do here.

But thanks for double checking!
