I'm not sure whether the patch ever could've worked. Firstly, the rich 
comparison operations were never called; I think perhaps due to some 
limitation in ExtenionClass. __cmp__ is called, but instead I just made 
the method explicit. Possibly this is better in Zope 2.7; I'm still 
testing with 2.6.4.

Then there's another problem; I think FieldHelpTopic is basically 
compared before Formulator (or the help system?) is fully initialized, 
so no groups or fields are found to compare (causing it to always succeed).

I'll try to revise the strategy to fix this problem..
