Well, I don't want to insist that it *must* be solved. But there's
different behaviour when running Emacs on GNU/Linux, or running on MS
Windows.
It is not an annoyance coming from a user's bug report; I've stumbled
over this when running tramp-tests.el under many different environments.
(expand-file-name "/:/~/path/./file") => "/:c:/~/path/file"
looks better, althoug the volume drive would still disturb me. But
that's my personal preference, the result might be OK on MS Windows.
Eli?
Best regards, Michael.
