tramp (2.0.36); tramp-rsh-end-of-line needs to be changed in my configuration.

[Greek0]

I'm using tramp with Emacs on Windows Xp. I want to connect to a linux
box via ssh using putty (0.53b). The ssh server is running OpenSSH_3.8p1
Debian 1:3.8p1-2. The ssh/sshx methods using the cygwin OpenSSH binaries
didn't work at all out-of-the-box, but I didn't dig into the problem,
instead I looked at putty/plink. Using plink the connection is opened,
the password is prompted, but after `stty -inlcr -echo kill '^U'` it
doesn't recognize the shell prompt any more, and after 30 seconds it
gives up. The reason is that tramp-send-command-internal uses
tramp-rsh-end-of-line (per default "\n") as line terminator, which seems
to expand to CRLF on windows. The server misinterprets this as 2 line
breaks, which results in 2 command prompts in the new stty mode: "$ $ ".
This is the case after every command given, since the wrong line
terminator is always used.

I fixed this by setting tramp-rsh-end-of-line to \r in my .emacs file,
everything works fine thereafter. The documentation to that variable
says it normally doesn't need to be changed, and a notification is
requested otherwise.
I guess it really is a windows specific problem that \n expands to 2
characters. Another way to fix it would be to tell stty to recognize
CRLF as one line-break instead of two, although I don't know how to do
this properly.

Below is the tramp debugging output and the tramp state. Please CC: me
on this thread, since I'm not subscribed to your mailing list.

Cheers,
