bug#64281: [Feature Request] Recognize “#” syntax when reading local-variables

[Shynur Xie]

For example, if I want to use UTF-8-UNIX only for files directly under
directory DIR, and those under DIR/SUBDIR/ or its subdirectories, I
can write this way:

    ((nil . ((subdirs . nil)
               . #1=((coding . utf-8-unix))))
     ("SUBDIR" . ((nil . #1#))))

If “#” can be recognized when reading local-variables, we can write
“((coding . utf-8-unix))” only once.  Thanks.
