Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I'm using emacs in conjunction with the latest cygwin tools.  When I
M-x rlogin to our local Gnu/Linux system directory completion fails on
absolute paths.  That is, after logging in I can complete directories
local to my (remote) home directory, but absolute paths do not
complete.  Nor does it work to cd to / and complete.

I have a custom-set-variables sexp setting
'(rlogin-directory-tracking-mode t).  When I attempt directory
completion I get an error because comint is composing my local windows
directory with the remote directory.  A stack trace shows:

Debugger entered--Lisp error: (file-error "Opening directory" "no such file or directory" "/mecklen@wolf:/home/mecklen/d:/usr/cygwin/")
  signal(file-error ("Opening directory" "no such file or directory" "/mecklen@wolf:/home/mecklen/d:/usr/cygwin/"))

  apply(ange-ftp-file-name-completion ("sour" "/mecklen@wolf:/home/mecklen/d:/usr/cygwin/"))
  ange-ftp-hook-function(file-name-completion "sour" "/mecklen@wolf:/home/mecklen/d:/usr/cygwin/")

  comint-dynamic-complete()

It appears the problem is in comint-dynamic-complete-as-filename but
that's as far as I've gone.
