The value of comint-password-prompt-regexp in the main trunk is both
simpler and more comprehensive of the value used in the RC branch.

In particular, the prompt of scp for a passphrase is handled on the
trunk, but not in the RC branch.

I suggest that this improvement be backported to the RC.

If it is clearly safe, please do it.

Hi, my prompt for my password for su in the shell of emacs is:
Mot de passe_:

with this password prompt, my password is not hidden, the only way i
found is starting emacs with LC_ALL=C

So i think the solution is to set the variable comint-password-prompt-regexp
but i don't know how to write Mot de passe_: in the regexp

It's original value is:
"\\(\\([Oo]ld \\|[Nn]ew \\|'s \\|login \\|Kerberos \\|CVS \\|UNIX \\| SMB \\|LDAP \\|\\[sudo] \\|^\\)[Pp]assword\\( (again)\\)?\\|pass phrase\\|\\(Enter \\|Repeat \\|Bad \\)?[Pp]assphrase\\)\\(?:, try again\\)?\\(?: for [^:]+\\)?:\\s *\\'"

Some body know how to insert Mot de passe_: into this regexp ?

Thank you.

On one of my systems, when using ssh in shell-mode (M-x shell), the
password prompt does not appear in the minibuffer but only in the
*shell* buffer directly under the ssh invocation, and the password is
not hidden when it's entered.  I've determined that reason is that the
password prompt string passed to comint-output-filter begins with a
carriage return character (^M), and when the rest of the prompt string
begins with "Password" (which it can on this system),
comint-password-prompt-regexp does not match it and thus
comint-watch-for-password-prompt returns nil instead of calling
comint-send-invisible.

So far I haven't found out where the carriage return is coming from,
maybe it's openssh (on the system where the carriage return occurs in
the prompt string I have openssh-8.2p1, on the system where the carriage
return does not occur openssh-7.9p1; if anyone knows the answer, or has
a suggestion how to find out, I'd appreciate hearing it).  Of course, I
can just customize comint-password-prompt-regexp to match the prompt
with the carriage return.  But I'm asking here because, if this should
be a more general issue, maybe the default value of
comint-password-prompt-regexp should be changed.  In bug#31075 Noam
Postavsky pondered whether eshell-password-prompt-regexp should replace
comint-password-prompt-regexp, noting that "the eshell regexp looks much
simpler".  And indeed, on the system where the carriage return occurs in
the prompt string, using ssh in the Emacs shell (M-x eshell) does use
the minibuffer for password input and it is hidden; and if I set
comint-password-prompt-regexp to eshell-password-prompt-regexp, then I
also get minibuffer hidden input in shell-mode.

So should comint-password-prompt-regexp be replaced by
eshell-password-prompt-regexp?
