[PATCH] Diff no longer accepts rev in which target didn't exist

This should really be two emails:

* Did we really intend to change "diff" to no longer accept a revision in which
the target did not exist? Once upon a time, "svn diff -r0:1 file-added-in-r1"
showed an all-lines-added diff of the file. Now, it errors out while trying to
trace the file's history back to r0.

* Here's a patch, for review, to fix up a test that relied on this behaviour.
(There's no harm in applying this patch even if we decide that the new
behaviour is a bug and subsequently fix it.)
