bug#44421: 27.1; run-python's SHOW argument has no effect

[dalanicolai]

Evaluate

    (run-python (python-shell-calculate-command) t nil)

the last argument 'nil' should prevent that the comint buffer is shown,
but the comint buffer shows nevertheless.

The solution is simple, namely, remove the before last line

    (pop-to-buffer buffer)

from the `run-pyton` function (printed below). The SHOW is already
passed to the 'python-shell-make-comint' function. The `pop-to-buffer`
makes the created comint buffer show, irrespective of the SHOW value.


(defun run-python (&optional cmd dedicated show)
  "Run an inferior Python process.

Argument CMD defaults to `python-shell-calculate-command' return
value.  When called interactively with `prefix-arg', it allows
the user to edit such value and choose whether the interpreter
should be DEDICATED for the current buffer.  When numeric prefix
arg is other than 0 or 4 do not SHOW.

For a given buffer and same values of DEDICATED, if a process is
already running for it, it will do nothing.  This means that if
the current buffer is using a global process, the user is still
able to switch it to use a dedicated one.

Runs the hook `inferior-python-mode-hook' after
`comint-mode-hook' is run.  (Type \\[describe-mode] in the
process buffer for a list of commands.)"
  (interactive
   (if current-prefix-arg
       (list
        (read-shell-command "Run Python: " (python-shell-calculate-
command))
        (y-or-n-p "Make dedicated process? ")
        (= (prefix-numeric-value current-prefix-arg) 4))
     (list (python-shell-calculate-command) nil t)))
  (let ((buffer
         (python-shell-make-comint
          (or cmd (python-shell-calculate-command))
          (python-shell-get-process-name dedicated) show)))
    (pop-to-buffer buffer)
    (get-buffer-process buffer)))
