I have obviously been using memory-destructive drugs.  Indeed I was wrong...
and I apologize for spreading bogus myth.... I would rather change my previous
statement to the form of "using two if's instead of the && would be clearer
and less confusing" instead of what I did state.  In some languages, the 
statement in question would present a problem of ambiguity, but thanks to
K&R, not in C.

At any rate, I am *never* going to loan out my K&R reference again, for if I
hadn't, I would've looked this up first.... :-(
