I checked pmwiki.org, and PSS() is documented here
 	http://pmwiki.org/wiki/PmWiki/Functions

with the following text:

 	PSS($string)

 	This function should always be used, passing parameters to
 	functions called via preg_replace. Especially when defining a
 	replacement with the Markup() function. It removes the escape in
 	front of quotation marks. This function is frequently used in
 	scripts/stdmarkup.php, for example in the definition of the
 	(:redirect:)-directive.

I found it slightly confusing... Maybe an example would clarify it?
(I've seen PSS() used quite often but never before understood when to 
use it).
