REVISION SUMMARY
  With this patch will all, and only, the nested foldings of a range
  (un)folded by right mouse click on the left hand icon border.
  
  The range itself keep untouched, not toggled.
  
  For convenience toggle the right button also a range which doesn't
  contain other folding ranges.
  
  The noted bug report request a slightly different behavior, but I think
  it's close enough to considered that as "fixed".
  
  BUG: 344414
  FIXED-IN: 5.58
