This uses the "--no-walk" flag that I never actually implemented (but I'm sure I mentioned it) to make "git show" be essentially the same thing as "git whatchanged --no-walk". It just refuses to add more interesting parents to the revision walking history, so you don't actually get any history, you just get the commit you asked for. I was going to add "--no-walk" as a real argument flag to git-rev-list too, but I'm not sure anybody actually needs it. Although it might be useful for porcelain, so I left the door open.
