Eddie Wyatt asks why this
	*a+=*b;
gives this message:
	warning ambiguous assigment: assignment op taken
The Walking Lint replies:
	Your compiler scans "+=" as two tokens rather than one.

Yeah, that's obviously what it's doing, but it's wrong.  The Rules say to
take the longest possible token you can, so "*a+=*b" should be parsed as
	* a += * b

Sounds like Eddie's found a compiler bug.
