Version 2.0.14 released.

(tramp-shell-prompt-pattern): New variable.
(tramp-actions-before-shell, tramp-multi-actions)
(tramp-find-shell, tramp-open-connection-multi)
(tramp-open-connection-setup-interactive-shell): Use it.
(tramp-open-connection-telnet, tramp-open-connection-rsh)
(tramp-open-connection-su): Mention `tramp-shell-prompt-pattern'
in the docstring.
(tramp-bug): Report `tramp-shell-prompt-pattern'.
(tramp-process-one-multi-action, tramp-process-one-action): Make
message clearer so people don't confuse it with Emacs asking them
a question if the regexp happens to end with "?".
(tramp-verbose): Change default value from 10 to 9.  Also change
some logging levels so that 10 is reserved for stuff which is
needed for debugging only, but 9 catches everything that people
might like to see in order to see that Tramp is actually working.
