Well, I wanted to use `with-suppressed-warnings', but this exists in
Emacs 27+ only.

It isn't Tramp code which changes frequently, so I guess we could keep
it as it is. And with Tramp 2.7 (Emacs 30), Emacs 26 won't be supported
any longer, and Tramp can get rid of it.

Let's work on a soonish Emacs 29 release ! :-)

Best regards, Michael.
