I don't get your point. If my patch works well (as you said above), why
do you want to change something else?

If you still have problems with my patch, please give me an exact recipe
what triggers the problem. I cannot reproduce the problem here, sorry.
A Tramp debug buffer, produced with tramp-verbose set to 6, would help.

Best regards, Michael.
