Subject: Re: [PATCH] git-gui: fix file name handling with non-empty prefix

Sorry for the late reply. I was able to reproduce the problem that you
were describing a while ago. And your patch indeed fixes it. It's a much
more elegant way of dealing with the "absolute vs relative" path problem
that I was trying to fix.

Thanks!

As for Pat, I'm not sure wha'ts going on with his email address. It was
working back in October, and his username still seems to be active over
at SourceForge... let's see if this email reaches him.

Here's a link for his reference just in case he missed your original email:
