Post-increments are evil, and not useful on nearly any processor (nowadays)
(the exception is ARM).
But they are _so_ very handy for the programmer :-)

The standard _has_ to be vague about a lot of things.  Not everything uses
two's complement, for example (although most programs assume all the world
is like that, and because of that, are not portable C).
