Oh.  You're correct, creation of a clashing name is a different
issue.

So, if I understand it correctly, you're wanting to prevent 
creation of pages with names that differ only in case from 
an existing page?

Yes, this can be done, but I think I'll leave it for a recipe
instead of doing this in the core (unless there's a huge
amount of demand for this feature).

Preventing the creation of a new group differing only
in case from an existing group is slightly harder, but
could also be done.

Actually, PmWiki does sufficient locking that this really
shouldn't be an issue.
