[Werner LEMBERG]

branch: master
commit bf8f100d2c46ccc04ed8cea8668d88c0f6c37317
Author: Werner Lemberg <address@hidden>
Commit: Werner Lemberg <address@hidden>

    [autofit] Provide dummy blue zone for pseudo script `none'.
    
    Even if the dummy hinter is used as the handler for `none' (which
    doesn't use blue zones), it is more consistent than the old value
    (which was 0), pointing to Arabic...
    
    * src/autofit/afblue.dat: Add `AF_BLUE_STRINGSET_NONE'.
    * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
    
    * src/autofit/afstyles.h (none_dflt): Use AF_BLUE_STRINGSET_NONE.
