I managed to get something *very* strange happening with the german  
corepages: after a few edits, it has become impossible to edit the  
Main page.

Not because of ACLs, but because request.getParameter() is returning  
the *page content without edits*.  This should NOT be happening.

I'm also a bit suspicious of WikiPage.clone(), which isn't cloning  
attributes or acls.  This could have some side effects somewhere.   
I'll be testing that...
