	Now understands non-unified diffs.  Some functionality moved into

	modify anything.  Only reposition point in the patched file if the
	patch succeeds.  Only pop up another window if POPUP is true.
	Emit a message describing what happened if successful, and at what
	line-offset.  Automatically detect reversed hunks and do something
	appropriate.

	(diff-filter-lines): Function removed.
	(diff-test-hunk): New function.
	(diff-goto-source): Rewritten in terms of diff-apply-hunk.
