Re: ¬ notation for not? Ref: Add a couple cells to lisp-prettify-symbols-alist

Hi Mark,

while your initiative is appreciated, AFAIK these symbols are not that 
canonic.

Implementing in core might draw subsequent requests suggesting the one 
or the other symbols instead, IMO keeping the pretty-print stuff in 
specialized packages is recommendable.

Cheers,

Andreas
