[ESS-bugs] ess-mode 5.2.12; R help error

[Richard M. Heiberger]

shell-strip-ctrl-m is an alias for `comint-strip-ctrl-m' in `comint'.

shell-strip-ctrl-m is part of Sqpe in essdsp6w.el
It is necessary on Windows to avoid the ^M when running an inferior Sqpe
process inside an emacs buffer.

I can't imagine why it should be necessary on Windows running R.
The line in essd-r.el
    (if ess-microsoft-p
	(setq default-process-coding-system '(undecided-dos . undecided-dos)))
is designed to suppress the ^M and correctly does so for me.

If it seems to be needed then I would check whether something is
wrong in the .emacs or in the site-start.el
