Johannes Schindelin 0087d7dfbe range-diff: consistently validate the arguments ...

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.
