Actually, the variable $GLOBALS['TmplDisplay']['PageLeftFmt'] is not yet  
defined when your skin.php file is loaded, because the wikitext has not yet  
been processed.

If this evaluates as true, it is probably because of the non-strict compare  
("unset variable" compared to a number will be internally considered a  
number, which is zero).

If you use a strict compare with === instead of ==, it will always evaluate  
as false.

Other skins redefine the '(:noleft:)' directives in order to be able to  
detect when they are used. For an example, see the Monobook skin.

At the moment, I don't see another way to do it.
