Sure, I'm fine with that -- it seems like a reasonable change.

I think you need to check that (get-buffer-process session) is non-nil
before calling process-name, otherwise you'll get (wrong-type-argument
processp nil).

Also it seems unnecessary to call `ess-make-buffer-current', as it's
already called by `ess-force-buffer-current' (which is called by
`ess-eval-region'). Though it doesn't hurt to call it, either.

Otherwise, this looks good to me.
