I thought it was redirecting to both actual and stdout (like a tee would) and jumped the gun (replying to your message) before verifying that it worked as I assumed.

The goal was to be able to capture stderr without suppressing it in the output of `sh t2400-*.sh -x`. The original solution I had did it's job while I was debugging an issue for the later patches in this set and I suppose I could have always used `-i` and looked inside `actual` myself after the git command failed.

Since the issues with the patchset I was having were resolved and there is an alternate way to debug the tests in the event they fail, I'm just going to drop these changes (and drop the `cat actual` changes).
