Ok, I've fixed it now. I also made slight changes to text.

The only reasons I could think of where:

* You get to define several "markup variables" using a single rule
* The variables are added to $GLOBALS, and thus available in FmtPageName() 
  etc. (Not that I know why that'd be useful).

Btw, if you look at the top of the page

	http://www.pmwiki.org/wiki/PmWiki/MarkupVariables

you'll see that I left a red note wondering what you need to do in order 
to make the "markup variables" available in the php code. The reason for 
this question is really that I linked to this page from PmWiki.Variables, 
where the PmWiki.Variables mostly discusses php-variables instead of 
markup variables.

So for instance, given that "{$Groupspaced}" works in the markup, what
does it take to be able to use it like this:

	$var = "Hello, the current group is $Groupspaced";

I'm guessing you'd have to do something like:

	$Groupspaced = FmtPageName("$Groupspaced", $pagename);
