Ah, that would explain why $single gets the ink and $cat's hidden away in the kitchen. It
still seems set enough for what I want of it, which is to be non-zero if "category" is in the
path.

$on_holiday? (you did ask.)

At bottom, definite declarations of that kind allow me to, with some confidence, set up
differences between a number of page views. I prefer on/off values and individual variables,
as that lets me set up views based on combinations that no one but I would care about.
