[ESS-bugs] ess-mode 5.3.5; M-x R messes up RET in new shells

[Tim Hesterberg]

Thanks for trying.  As you probably saw, I sent a note to ess-help

I think it is a combination of:
(1) M-x R causing subsequent new shells to use Windows eol sequences
  carriage return-line feed
(2) bash not accepting windows eol sequences.

The problem still occurs if I remove these three lines from site-start.el:
  (setenv "SHELL" (concat where "cygwin/bin/bash.exe"))
  (setenv "COMSPEC" (concat where "cygwin/bin/bash.exe"))
  (setq shell-file-name (concat where "cygwin/bin/bash.exe"))
and restart emacs with no-init-file; shells started before M-x R work,
and those started afterward do not.  In this case
'M-x getenv SHELL' gives
  d:/emacs/emacs-22.1/bin/cmdproxy.exe
'M-x getenv COMSPEC' and shell-file-name still both give
  d:/cygwin/bin/bash.exe
If I then do
  (setenv "SHELL" "c:/windows/system32/cmd.exe")
  (setenv "COMSPEC" "c:/windows/system32/cmd.exe")
  (setq shell-file-name "c:/windows/system32/cmd.exe")
then M-x shell starts a DOS cmd shell, which works (to the extent
that one can say that a DOS cmd shell works).
