Oh.. this might explain quite a few bugs actually. I'm guessing this is
not a fact that's well known...  PmWiki.BasicVariables could do with a
note about this as well. Would you say that $pagename deserves it's own 
page just like FmtPageName()?

What's the recommended way for scripts to deal with this?  (I'm talking
about scripts that might be invoked by config.php)
