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 kept untouched, not toggled.
However, for convenience toggle the right button also a range which
doesn't contain other folding ranges.
- Described action is also available in "View->Code Folding" menu as "Toggle Contained Nodes"
- Old two actions "Fold/Unfold Current Node" are replaced by "Toggle Current Node"
The noted bug report request a slightly different behavior, but I think
it's close enough to considered that as "fixed".
