Expanding a quoted file name works wrong on w32 systems. With Emacs
running on ‘gnu/linux’, there is

(expand-file-name "/:~/path/./file")
=> "/:~/path/file"

This is correct. With Emacs running on ‘windows-nt’, there is

(expand-file-name "/:~/path/./file")
=> "/:c:/Users/lb01177/AppData/Roaming/path/file"

I would expect the same result as above, keeping the tilde unchanged. My
Emacs version on the ‘windows-nt’ system is

GNU Emacs 25.1.1 (x86_64-w64-mingw32)
 of 2016-09-17

In GNU Emacs 26.0.50.7 (x86_64-pc-linux-gnu, GTK+ Version 2.24.30)
