Ok, it's fixed now and forever. There is ess-R-smart-operators variable
which can be t to activate the smart-comma (and all other smart
operators to come) in both ESS and iESS. It's nil by default. In the
future it will also allow a list to explicitly enumerate desired smart
operators for the specific mode.

Handy-command invocation on "," immediately after the prompt stays though.

I think something like that is already in ESS but I cannot find it nor
remember the function.

Your idea suggest yet another new feature. Imagine that not the user,
but Emacs goes back automatically and corrects all the mess. It could be
invoked by SPACE key or it could be triggered by an idle timer.

You type


and on next SPC it transforms into

tf <- foo %in% boo == zoo

Sounds pretty cool to me - doesn't interfere with the user's habits and
still corrects everything. It's even faster since you don't have to type
spaces :-)
