Plain AND is simple and goes pretty much all the way back to Boole, if not
further. In contrast, short-circuit AND has dicey semantics and is a relative
newcomer. Although it's awkward that C uses "&" for both plain and
integer-bitwise AND, for booleans I mildly prefer "&" to "&&" when either will
do, if only to remind readers of "&&"'s problems.
