I used it on woe32 because otherwise I saw "^M" at the end of lines of
program output in the comint buffers.

yes.

I think this is a bug in ess-mode, I do not see this problem with shell,
lisp and others.

I am not sure if
(add-hook 'comint-output-filter-functions 'comint-strip-ctrl-m)
is still necessary on woe32 (luckily, I no longer have access to a woe32
machine), so, for now, I will just comment that add-hook from my .emacs.

I suggest that the ess maintainers take a look at the problem though.
even if comint-strip-ctrl-m is completely obsolete, other hooks may
assume that the current buffer does not change inside comint-send-input
and you will be bitten by this in the future.
