[ESS] XEmacs, UNIX, ESS

Sorry to jump into the conversation, being a complete emacs lisp ignorant.

push-line-other-window is really neat (and I just added it to my
.emacs). However, if I have more than two windows, I find the behavior
disconcerting. A while ago, I found the following solution, which I
added to my .emacs. It sends the marked line (which can be in any
window) to a shell process, and shows the output (if there is anything
to be shown). What I do not like is that it will not use the shell
process window if I have one open already.

;; Take entire current line and execute it as a shell command:
;; from http://linux.hostweb.com/TopicMessages/comp.os.linux.misc/1859693/25/Default.aspx
 (defun my-execute-line ()
   "Execute the line the cursor is on in a subshell"
   (interactive)
   (beginning-of-line)
   (if (eobp) (error "End of buffer"))
   (require 'sh-script)
   (let ((beg (point)))
     (forward-line 1)
     (sh-execute-region beg (point))))
;;; RDU:
;;; I'd like this to work as in ESS, but I can't simply
;;; do a global-set-key because that would break ESS, the python-ess like, etc.
;;; But I don't want them local now, because I sometimes execute pieces
;;; of shell code that are in arbitrary files (R, C, python, etc).
(global-set-key "\C-cy" 'my-execute-line)
(global-set-key "\C-cr" 'sh-execute-region)

HTH,

R.
