But what are SCI_SETMARGINTYPEN(SC_MARGIN_BACK) and 
SC_MARGIN_FORE supposed to do?

Yes, I knew that. I did get it to work. The line with 
SC_FOLDLEVELHEADERFLAG should still have the previous fold level. So for 
instance

SCI_SETFOLDLEVEL(0, SC_FOLDLEVELBASE | SC_FOLDLEVELHEADERFLAG)
SCI_SETFOLDLEVEL(1, SC_FOLDLEVELBASE+1)

appears to work for a one line fold, starting at line 1.

So it does work "from the container".

Thanks!
