[Werner LEMBERG]

branch: master
commit 68fb4789a582561606fafbe51e7a217598bb35ec
Author: Werner Lemberg <address@hidden>
Commit: Werner Lemberg <address@hidden>

    * src/autofit/afhints.c (af_get_segment_index): Fix it.
    
    The old code was too simple, returning invalid values in most cases
    where a segment crosses the contour start.
