Subject: 31.0.50; TRAMP failure with `tramp-use-connection-share' set to nil
Date: Tue, 25 Feb 2025 15:01:32 +0100

Hi (again) Michael,

Currently, TRAMP is failing with `tramp-use-connection-share' set to nil
(my setting because I manage ControlMaster in my own .ssh/config).  How
to reproduce this:

             - emacs -Q
             - M-: (setopt tramp-use-connection-share nil) <RET>
             - C-x C-f /-:somewhere: <RET>

Now I get the following error:

tramp-signal-hook-function: Wrong type argument: "char-or-string-p nil"

The culprit seems to be the cond in `tramp-ssh-or-plink-options' which
could end up returning nil.

Best regards,
