I have an update to CGI::Wiki::Kwiki to integrate it with my diffing module
CGI::Wiki::Plugin::Diff.
I attach a tar kit with the full change, including a new template file and 
updates to CHANGES, MANIFEST, Build.PL etc. 
I do not have the facilities to run this up as a full wiki site :(. 
Please can some of you have a go at break^Wtesting it.
Just in case mailmangler mangles the tarball, I am including the main body 
of the change, as a patch to Kwiki.pm:
