"git diff <tree>{3,}": do not reverse order of arguments

According to the message of commit 0fe7c1de16f71312e6adac4b85bddf0d62a47168,
"git diff" with three or more trees expects the merged tree first followed by
the parents, in order.  However, this command reversed the order of its
arguments, resulting in confusing diffs.  A comment /* Again, the revs are all
reverse */ suggested there was a reason for this, but I can't figure out the
reason, so I removed the reversal of the arguments.  Test case included.
