redirection of help output to a separate buffer in comint (python)

[Sam Steingold]

Hi,

When I type "help('foo')" in the Python interaction buffer, the help
output appears in the "*Help(Python)*" buffer instead of the comint
buffer itself (and, yes, this is the desired behavior).

However, I cannot figure out what code implements it.

E.g., when I do

--8<---------------cut here---------------start------------->8---
(defun python-describe-at-point (symbol process)
  (interactive (list (python-info-current-symbol)
                     (python-shell-get-process)))
  (comint-send-string process (concat "help('" symbol "')\n")))
--8<---------------cut here---------------end--------------->8---

the help is displayed in the comint buffer, not the *Help(Python)*
buffer.

Any pointers would be appreciated.

Thanks.

PS. I thought that `comint-redirect-*' would be used, but it appears
that it is not.
