Replace term "path" with "localname" unless it is used for a
search path.
(tramp-handle-expand-file-name): Allow ".." to cross host
boundaries.
(tramp-open-connection-setup-interactive-shell): Unset $ENV in
addition to setting $PS1 when starting the Bourne-ish shell. Some
sh implementations (eg, bash when called as sh) read the file
named there on startup, which could clobber $PS1.
(tramp-do-copy-or-rename-file-one-local): New function. Not
implemented. Not used. Should invoke rcp or scp directly to keep
the time.
