How does this work?  It's exactly what I found in my testing, but it
seems strange.  If (:if:) gets processed *before* (:include:) then how
come the (:if ...:) within those included pages gets rendered?  It
seems that the (:if:) directive in  the included text wouldn't even
exist until after the if rule had already been executed...

I'm not arguing that it happens - I verify that you are exactly
correct on my own system.  I'm just confused *how* it happens...
