Thanks for the feedback. Since I have no *BSD machine, I couldn't test
the patch; it was rather a shot into the dark.

I've pushed the patch, slightly modified, to the Emacs and Tramp
repositories. It won't appear with Emacs 27.1, because it is too late to
commit such serious changes so close to its release; but I will merge it
into the emacs-27 codebase after Emacs 27.1 has been released.

The next GNU ELPA Tramp release, 2.4.3.2, will carry this patch. It will
appear in a couple of weeks.

Best regards, Michael.
