OK, now that we have opened up the "style" issue with !p vs p != NULL (sic),
how about another:

Which operator (pre-increment or post-increment) do you use when the side-
effect is the only desired action and the result is discarded, i.e.

	for (i=0; i<MAX; ++i)
vs
	for (i=0; i<MAX; i++)

or
	++counter;	vs	counter++;

Personally, the use of post-increment operators here drives me crazy.  They
have the added meaning of returning the value of the incremented lvalue
before the increment.  If this is just thrown away, why do it?  Also, for
some reason (buried deep within my convoluted brain), when quickly scanning
code, I tend to recognize ++counter much faster than counter++.
