This patch lets `range-diff` validate the arguments not only when
invoked with one or two arguments, but also in the code path where three
arguments are handled.
While at it, we now use `usage_msg_opt*()` consistently.

Very nice. The updated series is worth having if only for this
step. Very very pleasing.
