#6 Folding

[Simon Strandgaard]

There exist many kinds of folding.
* manual specifying region which to fold.
* auto folding by letting an regex identifying start/stop
marks.

The folding state will be remembered with the file, so
next time you open the file you will see the file the
same way you left it. But it is not stored in the file
because it has to be CVS friendly.
