[PATCH 1/3] Prepare for non-interactive merge-preserving rebase

From: Andreas Ericsson <ae@op5.se>
Date: Sep 23, 2008, 20:57 UTC
Message-ID: <48D95836.6040200@op5.se>

This patch adds two tests (really three, but one of them just handles setup) which we currently expect to fail.

One of them tests "git rebase -p", without the -i flag, to make sure it works without phony editors and suchlike.

The other tests "git pull --rebase --preserve-merges" to make sure that the same functionality exists there.

The test was originally written by Stephen Habermann <stephen@exigencecorp.com> but has been significantly modified since its creation.

Stephen, I had to modify the tests a bit to get them to work with how I implemented the merge-preserving rebase, and also to remove a lot of the cruft that was previously in there. Hope you're ok with the attribution in the commit message.
