Cute, but worries me a bit because normally -W options aren't
syntax-checked at all by the command line processing code -- only by
the warnings module (because the syntax is too complex).  And this
means that you don't get a warning about a bogus option at all if no
warnings are ever issued.  This would mean that a misspelling of -Wdiv
would cause mysterious silence.

Command line options aren't in such short demand that I can't pick a
new letter.
