* net/tramp-sh.el (tramp-remote-process-environment): Remove
HISTFILE and HISTSIZE; it's too late to set them here.  Add
:version entry.
(tramp-open-shell): Do not let-bind `tramp-end-of-output'.  Add
"HISTSIZE=/dev/null" to the shell's env arguments.  Do not send
extra "PSx=..." commands.
(tramp-maybe-open-connection): Setenv HISTFILE to /dev/null.
