[Pmwiki-users] lower case characters in group names?

[Philip Jägenstedt]

Hello!

I want to have lower case characters in group names so that I can use 
groups for different languages, e.g. "en" and "sv". I want them to be 
lowercase because these language codes are always written in lowercase 
and I want the URIs to look right.

When I try to visit 
http://www.digifri.studorg.liu.se/pmwiki-2.0.devel13/pmwiki.php/sv/Wikifri 
on an installation without messing with the groups (but now I have, so 
you won't see the same!) I get to a page without a title that says 
"Describe / here." that links to
http://www.digifri.studorg.liu.se/pmwiki-2.0.devel13/pmwiki.php//

Setting
$GroupPattern = '[\\w]+(?:-\\w+)*';
in my config.php gives me a page with the title Wikifri saying "Describe 
Wikifri? here." with a link to 
http://www.digifri.studorg.liu.se/pmwiki-2.0.devel13/pmwiki.php/Sv/Wikifri?action=edit.

As you see, sv has been capitalized to Sv in the URI. I've looked 
through pmwiki.php but could immediately find any code that does this, 
and don't really know where to look. Help with this is appreciated!
