Re: Fix per-directory exclude handing for "git add"

I guess really the output of "git status" (or "git runstatus") is
more significant since that's what we'd normally be running (that's
presumably what "git gui" and similar tools run, though perhaps they
use "git ls-files"---probably the underlying code's the same, I
guess).

Bah.  "git status" also works correctly, I think.  I was just testing
stupidly.
