[ESS-bugs] underscore randomly stops doing <-

This happens often to me 5times in a month. The underscore stops working
as <- when I am using R in Emacs.

I quit ("q()") and started R console again, but no use. I looked to
restart the mode by (`M-x ess-mode`), but I couldn't find that option. I
decided to change the variable `ess-toggle-underscore nil` but didn't
find that variable when I did "C-h v".
