bug#23936: 25.1.50; shell-command shell-command-on-region doc fix

[Tino Calancha <tino.calancha@gmail.com>]

There is another wrong sentence in the doc strings for
shell-command[-on-region]

The output buffer is not deleted: the code killing that buffer was
commented:

;; It is rude to delete a buffer which the command is not using.
;; Don't kill: there might be useful info in the undo-log.

* lisp/simple.el (shell-command, shell-command-on-region): These
commands never delete the buffer '*Shell-Command Output*'; update
their doc strings (Bug#23936).
