0.8.4.14:

	Fix suboptimality reported by piso on #lisp
	... catch bogus types like (fixnum 10) before they get too far
		in the type system
	... doesn't work for logically-built-in-but-made-by-PCL types
		(yet)
	Comment out newly-broken assertion that constant multiplies
		don't produce compiler-notes
	... if that's all that broke, count your lucky stars :-)

   * fixed bug 141b: printing backquoted information readably and prettily
     inserts a space where necessary.
+  * bug fix: obviously wrong type specifiers such as (FIXNUM 1) or
+    (CHARACTER 10) are now reported as errors, rather than propagated
+    as unknown types.  (reported by piso on #lisp)
   * compiler enhancement: SIGNUM is now better able to derive the type
     of its result.
   * fixed some bugs revealed by Paul Dietz' test suite:
