+	* src/autofit/afhints.c, src/autofit/afmodule.c,
+	src/autofit/aftypes.h: adding more debug messages and fixing a small
+	bug in af_compute_direction which produced garbage by missing lots of
+	segments

 2006-10-24  Werner Lemberg  <wl@gnu.org>
 
 	* src/cff/cffload.c (cff_encoding_load): Remove unused variable.
