bug#63246: 30.0.50; TRAMP with doas multi-hops

[Manuel Giraud]

Hi,

I have a bug when trying to access a remote ssh host and then doas on
it.  Here is the recipe starting from 'emacs -Q':

     C-x C-f /ssh:host|doas::
     ;; Enter wrong doas password (ssh authentication is done with a
     ;; key)

Here, I get a connection error because the doas authentication failed.
With another linux host and with sudo, Emacs re-ask for the password if
I entered a wrong one.

Best regards,
