this is a nice..

I'm sure I'm not 100% uptodate on this topic,
*but* I know that we had introduced the "jump to END OF BUFFER of
iESS" (typically *R*)
very much on purpose because ESS users wanted it...
I think I have used this quite often, because indeed I most of the
time wanted to jump to EOB in *R* when coming from the script file.
It could be that this is much less important now that (I think) the
iESS (comint) buffer is scrolled automatically and point typically is
at EOB in that buffer ....
Is this the reason why you (and others) think that "jump to EOB" is no
longer much needed ?
