jEdit has some fold support, but the Isabelle/jEdit version of it is still 
in the adhoc state of 2010, i.e. very basic and hardly usable.

I tried again for the coming release to make more of this work, but I got 
entangled into too many other problems.  This is also the reason, why I 
have started to spend signigicant time to make a clear slate, and 
eliminate the remaining uses of Proof General first.
