Subject: false positives from git diff-index when used with --git-dir
Message-ID: <AANLkTimyeE=OLdC0Zzdnidr_dssFfkMzS+r_39dYUVxz@mail.gmail.com>

Hi, list!

$ git --version
git version 1.7.3.1

$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 10.10
Release:	10.10
Codename:	maverick

I'm *sometimes* (once in about ten times I use it -- repository
changes between invocations of course) getting false positives from
git diff-index when I invoke git from another directory:

git --git-dir=path/to/.git --work-tree=path/to update-index -q --refresh
git --git-dir=path/to/.git --work-tree=path/to diff-index --exit-code
--quiet HEAD

This is *really* annoying and really kills the benifits from my
workflow automation scripts.

Unfortunately I can't find a reproducible use case for this bug.

Is there anything I can do to help catch it?

Thanks,
Alexander.
