Hi Lennart,

Sorry for the late reply.

what black magic do we need to use to specify what Cygwin calls
codepage ansi or oem in Emacs?

Cygwin just uses the MS Windows naming conventions here.  "ANSI" is
the codepage that the graphics subsystem uses and "OEM" is the default
codepage for console I/O, like CMD.EXE uses it, e.g.

Emacs should have the coding system for the "ANSI" codepage in the
variable locale-coding-system, I think.

Thanks Benjamin. I tested this with both Cygwin and MSYS and it seems to work. So now here is how the end of defun shell could look like at the moment:

      (when (eq system-type 'windows-nt)
        (let* ((shell-file-name prog)
               (proc (get-buffer-process (current-buffer)))
               (fullprog (executable-find prog))
(cp-out (read (format "cp%s" (w32-get-console-output-codepage)))) (cp-out-dos (coding-system-change-eol-conversion cp-out 'dos)) (cp-out-unix (coding-system-change-eol-conversion cp-out 'unix))
               (cp-in  (read (format "cp%s" (w32-get-console-codepage))))
               (cp-in-dos (coding-system-change-eol-conversion cp-in 'dos))
(cp-in-unix (coding-system-change-eol-conversion cp-in 'unix)) (cp-locale-dos (coding-system-change-eol-conversion locale-coding-system 'dos)) (cp-locale-unix (coding-system-change-eol-conversion locale-coding-system 'unix)))
            (set-process-coding-system proc cp-out-dos cp-in-unix))
           ((string-match "/msys/" fullprog)
            (message "think it is MSYS...")
            (set-process-coding-system proc cp-locale-dos cp-locale-unix))
           ((string-match "/cygwin/" fullprog)
            (message "think it is Cygwin...")
            (set-process-coding-system proc cp-locale-dos cp-locale-unix))
            (message "unrecognized shell program: %s" fullprog))

Maybe we could install something like this and get on with the quesion about file name completion which as we earlier saw also is broken on w32?

I would however want to add one thing to the above: The possibility to explicitly set the coding system for the interactive shell.

And maybe the tests for Cygwin and MSYS should be enhanced, but let us take some steps forward please!
