[Emacs-diffs] master 438b98e: Don't mirror slashes in convert-standard-filename on MS-Windows

branch: master
commit 438b98e5b70c55129453870b870a139c4a4a77fd

    Don't mirror slashes in convert-standard-filename on MS-Windows
    
    * lisp/w32-fns.el (w32-convert-standard-filename): Don't mirror
    slashes into backslashes.  This avoids producing ugly file names,
    and is deemed no longer necessary, and should certainly be
    unrelated to which shell is in use.
