Tentative built-in "git show"

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.
