Rlogin patch for global option flags

[Michael Mauger]

I have an elisp program to call `ssh' a la `rlogin'.  Essentially it sets
the `rlogin-program' variable to `ssh' and calls `rlogin'.  The problem
is that ssh (cygwin's port) running with the w32 version of CVS Emacs
needs the option `-tt' prior to the host name to open the connection
correctly.  The problem is that the `rlogin' function treats the `-tt' as
the remote host name because it is the first argument.  

The following patch modifies the `rlogin' function command line
interpretation by assuming that the second argument is the remote
hostname if the first argument starts with a dash.

Please review and apply if deemed suitable.
