Version 2.0.12 released.

(tramp-find-shell, tramp-open-connection-setup-interactive-shell):
Comment out possibly obsolete "echo hello" commands.
(tramp-run-real-handler): If operation is
`ange-ftp-hook-function', use first arg as the real operation.
(tramp-check-ls-commands): Use / instead of \ as directory
separator.  (Relevant for XEmacs on Windows.)
(tramp-maybe-open-connection): Use tramp-wait-for-output when
waiting for the "are you awake" command.  Use a different string
for the "are you awake" command.
(tramp-send-command): New optional arg NEVEROPEN means to never
invoke tramp-maybe-open-connection.
(tramp-maybe-open-connection): Use it
