Possible d/f conflict bug or regression

Hi,

When doing something like:

mkdir testdir &&
        cd testdir &&
        touch foo &&
        git init &&
        git add . &&
        git commit -m 'Initial commit.' &&
        rm foo &&
        mkdir foo &&
        git commit -a -m 'Test.'

I get:

Initialized empty Git repository in .git/
Created initial commit 3f945ca: Initial commit.
 0 files changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 foo
fatal: unable to index file foo

I think it's quite bad that it doesn't work.

It seems it also doesn't work when adding "touch foo/bar" before "git commit -a -m 'Test.'".

I used:

$ git --version git version 1.5.5.rc2

It worked with 1.5.3 and I bisected it to the git commit port to C:

commit f5bbc3225c4b073a7ff3218164a0c820299bc9c6
Author: Kristian H<C3><B8>gsberg <krh@redhat.com>
Date:   Thu Nov 8 11:59:00 2007 -0500

    Port git commit to C.

    This makes git commit a builtin and moves git-commit.sh to
    contrib/examples.  This also removes the git-runstatus
    helper, which was mostly just a git-status.sh implementation detail.

Thanks, Christian.
