[pmwiki-users] Category Markup

[DaveG]

I abandoned the regex from hell, and used a function instead :) Is there 
such a thing as ReplaceOnEdit?

On http://www.pmwiki.org/wiki/PmWiki/EditVariables I tried to put a link 
to Cookbook/ROSPatterns. If I put the link on the same line/paragraph as 
the existing text, the link is undefined. Putting it on a new paragraph 
works fine. I suspect it's to do with the sample prior which has 
unclosed ]]?

Just out of interest would a regex have been possible?
