CC: CWH at MIT-MC, NIL at MIT-MC, INFO-LISPM at MIT-MC

This is already fixed in the NIL syntax, and probably can't be moved
as easily as the other thins which were experimental (infinities).
Why not stick with #.?  Its already done in LIBLSP;SHARPM, which
we ought to adverrtize soon as an "emerging" standard (and hopefully
make autoloadable in maclisp if no one really objects).
