%= operator missing in docs

mmcp42:
think I'll stick to "easier-to-read" rather than save a byte or two

Note that the bytes you save are only in your source code. Both should compile to the same object code. There is no performance benefit to the more compact version.

There's a lot to be said for easier to read. I've been programming for 30 years and "x%=3" would make me stop and scratch my heat.
