This can't possibly work. 'pagename' is an INPUT field. It can end up holding
absolutely anything. Passing the default value through wikiword won't fix that.

Doing some testing on my own site, this looks to be due to an actual error in
PmWiki's URL parsing. Specifically these work as expected:

  www.example.com?n=Blog.ThisIsATest?action=edit
  www.example.com?n=Blog.This+is+a+test

But this doesn't:

  www.example.com?n=Blog.This+is+a+test?action=edit

I did a quick look through pmwiki.php, but I couldn't see any obvious place
where things could be going wrong.
