Interesting concept. Thanks for the explanations...

OK, I've "cloned" what's done for `comint-postoutput-scroll-to-bottom' and
`comint-watch-for-password-prompt', present in my
`comint-output-filter-functions', by adding an optional `_string' argument:
--8<---------------cut here---------------start------------->8---
(defun my-rename-buffer-to-curdir (&optional _string)
"Change Shell buffer's name to current directory."
(message "%s" default-directory)
(rename-buffer (concat "*shell " default-directory "*")))
(add-hook 'shell-mode-hook 'my-rename-buffer-to-curdir)
(add-hook 'comint-output-filter-functions 'my-rename-buffer-to-curdir nil t)
--8<---------------cut here---------------end--------------->8---
However, that does not change the end result: the name of the buffer is
unchanged.
Should I report this as an Emacs bug?
Best regards,
Seb
