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.
