changes in sbcl-0.8.17 relative to sbcl-0.8.16:
+ * the system now has rudimentary external-format support; the
+ primary user-visible change at this time is that characters with
+ the high bit set (such as lower-case-e-acute) will print correctly
+ to a terminal in a UTF-8 environment.
* minor incompatible change: BASE-CHAR no longer names a class;
however, CHARACTER continues to do so, as required by ANSI.
* minor incompatible change: SB-DEBUG:*DEBUG-PRINT-FOO* variables
