Wait wait, the bug bisects to

490544b (get_cwd_relative(): do not misinterpret suffix as subdirectory,
2010-05-22)

for me, using

git bisect run sh -c "make || exit 125; cd /etc; GIT_DIR=/tmp/a/.git
~/src/git/git-add fstab || exit 1"

and a repo in /tmp/a/.git with core.worktree set to "/".

The issue is that in get_relative_cwd() of dir.c, "dir" (and maybe
("cwd") may or may not end in "/", so even with dir="/etc/" and
cwd="/etc" we would not recognize we are within the repo. Patch for that
is coming.

Note that by doing something like the above, we can test / without being
root as long as we have files there which we can rely on being readable,
or can rely on /tmp being there.
