possible regression (or me abusing git) in v1.5.5

Hello,

After upgrading to v1.5.5, I noticed a change in the way that git treats symbolic links.

Git will follow symbolic links to directories when they were added as follows

$ git init $ mkdir foo $ touch foo/bar $ ln -s foo foo1 $ git add foo1/ # Note the trailing slash above.

In v1.5.5 (but not v1.5.4.5 and earlier), $ git add -u will remove foo1/bar from the index.

I have bisected this down to f58dbf (diff-files: careful when inspecting work tree items).

The ability for git to follow links (instead of recording them) was a
useful feature for me, but I may have been abusing this "feature".  If
that is the consensus, it might make sense to have
$ git add foo1
and
$ git add foo1/
 behave the same way?

Thanks, Tarmigan
