#1679 binary command and arg checking
It would be nice if [binary format] would do some
argument checking, and throw errors if the value
is incompatible with the format.
For example, the following script should cause an
error:
binary format s 40000
Since the value of 16-bit signed words is -32768 to
32767, the value of 40000 is illegal.

I'm not convinced that's the right thing to do, especially
since there may be existing code that depends on being able
to convert (effectively) unsigned shorts into 16-bit values.
The real stickiness comes when you start to consider what's
going on with 32-bit systems. I think I'll put this on the
back burner for a while...

Review of the documentation indicates that the current behaviour (taking the low-order 16-bits of
whatever integers are supplied) is correct. Changing this would not be backward compatible.
