Simplify man(7) validation:

Drop pre-handlers, they were almost unused.
Drop the needless complexity of allowing more than one post-handler.

This saves one internal interface function, one static function, one
private struct definition, sixteen static arrays, and 45 lines of code.
No functional change.
