21.x feature request: windows shortcut support

[Jari Aalto+mail.emacs]

    In Windows, it is possible to create shortcuts that refer to
    the original files. The cygwin development team already uses
    windows shortcuts as substitute for native Unix symlinks.

    I'd very much hope that Emacs would also offer support
    for Windows shortcuts so that the actual file pointed by
    shortcut is loaded.

    Example: I keep all my files under CVS version control

        ~/confing/env/.mailcap
   
    In Unix I symlink this file to

        bash-unix$ ln -s ~/confing/env/.mailcap ~/.mailcap

    And I can do exactly the same under Windows/Cygwin

        bash-cygwin$ cat ~/.mailcap

    But if I try to load the same file with Emacs 20.7, the link
    file (.mailcap.lnk) itself is loaded and displayed in binary 
    format. The binary format is easily parseable and support
    in 21.x could be easily provided at C-level.
