I'm wondering if this will also solve the problem of when you have a
pagelist and a searchbox on the same page.  I remember having problems

How does one tap into the variables passed to it?  Never heard of any
recipes using input like that, but it could be interesting...

My server (where the problem is) is php4.4.4.  My home machine where
it works it 4.4.2.  Both are using pmwiki-2.2.0-beta12.  Thanks much
for fixing this!
