I've been trying to set the foldingStartMarker and foldingStopMarker  
for a simplified variant of Markdown but have had no success. The  
file would look something like this

# First heading #

Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Suspendisse  
vel nunc.
Suspendisse egestas erat vitae pede. Phasellus quis libero et tortor  
commodo
auctor. Sed et erat. Aliquam sed lectus. Fusce semper elit nec ipsum.  
Morbi
sem nisl, tristique id, venenatis quis, gravida sed, neque. Etiam ut
felis. Curabitur leo magna, molestie vitae, blandit et, fringilla  
vitae, purus.

# Second heading #

Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Suspendisse  
vel nunc.
Suspendisse egestas erat vitae pede. Phasellus quis libero et tortor  
commodo
auctor. Sed et erat.

Aliquam sed lectus. Fusce semper elit nec ipsum. Morbi
sem nisl, tristique id, venenatis quis, gravida sed, neque. Etiam ut
felis. Curabitur leo magna, molestie vitae, blandit et, fringilla  
vitae, purus.

# Third heading #

etc


I'd like to fold so that only the heading lines show.

The foldingStartMarker is easy:

     foldingStartMarker = '^# +';

But I can't get a foldingStopMarker that works. What I'd like to use  
is a blank line followed by a positive lookahead to a line that  
starts with a hash and a space, but

     foldingStopMarker = '^$\n(?=^# +)';

doesn't work, even though that regex works in the Find dialog box.

Are the start and stop markers restricted to single line patterns?  
The manual suggests that, but it isn't explicit. Does anyone have any  
ideas?
