Possible bug with git status in 1.7.0

Hi,

if you have a submodule and the submodule contains
untracked files, "git status" in 1.7.0 keeps showing
the module as modified.

But of of course it is useless to "git add" the module
or to try to "git  commit -a", since the index entry is ok

I do not know if this is an intended behavior, but it
looks different from 1.6.6.1.
