bug#22561: 25.0.90; dired alphabetic sort of listing handles leading '.' strangely on MS Windows

[Kevin Gallagher]

In M.S. Windows 7, Started Emacs with

C:\emacs-25.0.90\bin\runemacs.exe -Q

Entered <C-x> <C-f> <RET>

The following listing of my home directory looks as follows

I believe the listing in Emacs 24.5 is preferable. It 25.0.90, it is as if the initial period in any file/directory entry is being ignored when sorting alphabetically. Also, upper and lower case are also being ignored.
