Neophyte's question raised re: p - (nf)

[BergerCA]

I understand the desire for uniform evaluation of expressions in various
versions in C.  There are plenty of things that make me uncomfortable as
well.  Expressions of the type
	s++ = ( s & 0x7f );
		and the like just LOOK dangerous.  I prefer the safer
approach of
	s &= 0x7f;
	s++;
		which may generate slightly less efficient code of known
semantics.
