Splicing macros after a dot.

(setsyntax '/~ 'splicing '(lambda () (read)))

(a b ~(c)) reads as (a b c)


(a b . ~(c)) read as (a b c) !!!

Now no matter what your splicing macro philosophy is, this has Got To Be Wrong.
As I see it the "right" thing to happen is for (a b . ~(c)) to be (a b . c).
Also (a b . ~nil) should be an error (Not a hunk, as it is now). Also ~(foo) at top level
should be the same as just foo, not ignored (/; can damn well return nil if it wants to
be ignored).  If someone makes these changes then there can be a lisp machine compatable
# macro, but not untill then.
