Version 2.0.9 released.

Version 2.0.9 released.
(tramp-bug): Add wording about additional info to include in bug
report.
(tramp-find-shell): Set $PS1 for invocation of second shell (for
tilde expansion).
(tramp-find-shell): Shell prompt must match at end of buffer.  Do
this also for fallback shell prompt.
(tramp-find-shell): More debugging output.
(tramp-find-inline-encoding): When checking the decoding command,
some commands fail when reading from /dev/null.  So we pass a
known string through the encoding command and pass that through
the decoding command.  So we know whether the decoding command can
deal with some real input.
