Make apropos's lookup use a find(1)-like expression. I'll write more on

this when it completes; this is to keep it in-tree.

Right now this uses prefix notation.  Ignore it.  I'll make this into
infix notation real soon.

The goal of this (exprcomp and exprexec) is to have arbitrary logical
expressions.
