In any case, the 'pager = "slynx -dump"' part is definitely
the culprit and it definitely is a leak from "S+ code for ESS"
(I'm pretty sure I had added to ESS aeons ago).
So, something in your Emacs initialization (typically inside
~/.emacs, but there are other possibilities) is the culprit.
Try the following:
1) Start Emacs
2) M-x R
3) C-h v ess-customize-alist
Should give about 20 lines of output in a *Help* buffer.
One of these 20+ lines is particularly interesting; for me it is
(inferior-ess-help-command . "help(\"%s\", htmlhelp=FALSE)\n")
and I bet that for you, it will contain the ominous "slynx ..."
