Actually, either function works, as PageVar calls PageTextVar. It is
probably mildly faster to call PageTextVar directly though.

Not sure about this. Is $pn globally available? Not sure, but it doesn't
look like it. I'd always thought $pagename referred to the current page
from within skin/config files.

That's correct when calling PageTextVar. But called from PageVar, then
the $:myvar format is used.
