Oh, I guess \Q doesn't work with variables like in perl; good to know. When I changed that to preg_quote(), those errors when away, so now it works with a section called "/".
Thanks again -Steve
Thank you!
Checked into SVN in r17736. Only tiny changes made were to add the '$wgParserTestFiles[] = ' line (which invokes the LST tests whenever parserTests is run and the extension is enabled), and update the format of the header line in the "Transcluded section headings create edit link to template" test to match the header format used in SVN head (which differs slightly from that used in 1.8 and earlier).
All the best, Nick.
