When I parenthesize to explain code to humans, rather than the compiler,
I feel that some added space (especially around complex sub-parenthesized
expressions) is valuable.  Now, since one goal of KNF is to make all code
look similar, issues of taste like that are exceedingly hard to regularize,
but KNF ought not to get in the way of code readability; if you _want_ the
IOCCC, I trust that you know where to find it.
