bug#40051: 26.3; comint-password-prompt-regexp

[Lutz Weber via Bug reports for GNU Emacs, the Swiss army knife of text editors]

In Emacs 26.3 in shell-mode with OpenBSD 6.6 with the doas command I am
being asked for a password.  The password entered is not hidden.

The workaround is to run this:
(require 'comint)
(setq comint-password-prompt-regexp
      (concat comint-password-prompt-regexp
              "\\|^.*doas.*password:\\s *\\'"))

This might be added to the defaults.  Thank you.

Could you show what the prompt you receive looks like?

Thank you for the reply:

* both samples show shell-mode (OpenBSD default shell KSH_VERSION='@(#)PD KSH v5.2.14 99/07/13.2')

** without workaround "emacs -Q":

user@leno1:~$ doas /sbin/mount /usb
doas /sbin/mount /usb
doas (user@leno1.example.home) password: PASSWORD

** with workaround:

user@leno1:~$ doas /sbin/mount /usb
doas /sbin/mount /usb
doas (user@leno1.example.home) password: (shows dots in minibuffer only as expected)

Just let me know when I can be of further help.
Lutz

I see that "doas" has been added to `comint-password-prompt-regexp' in
more recent Emacs versions, so I'm going to go ahead and guess that this
has been fixed by now, and I'm closing this bug report.
