[ESS] R code folding with hideshow-org.el

[Shane Celis]

In fact hideshow-org uses 'hs-toggle-hiding.  It's not separate from  
hideshow; it works on top of hideshow.  And I respect your caution  
when it comes to messing with tab.  It remains to be seen whether it's  
workable.  It may be that C-tab or some other such key may be better  
appropriated.  Or that one might want to tab twice before it does  
folding.  I'm experimenting and happy to hear suggestions to see what  
works.
