Sorry, no ))

I write

(defun my-strip-last-cr (str)
  (pp str)
  (if (> (length str) 0)
      (if (equal (substring str -1) "\r")
          (progn (message "yyy") (substring str 0 -1))
        str)
    ""
    ) )

(defun my-shell-input-filter nil (add-to-list 
'comint-input-filter-functions 'my-strip-last-cr))

(add-hook 'shell-mode-hook 'my-shell-input-filter)

M-x shell ls RET
bash: $'ls\r': команда не найдена

In *Message* buffer I get:

#("ls\n" 0 2
  (fontified t))

So no any \r pass to filter!!

Also I try recent bash specific Cygwin settings: "set -o igncr" without 
happiness.

If I type whitespace char after ls/pwd - all OK.

I don't find any relevant settings in shell.el and comint.el by 
searching "\r" or "^M"
and don't know how further debug issue.
