Comment (by logi):

 OK, this is actually fixed on master. I'm looking at this code which seems
 to be a bit more sophisticated than my line distinguishing -0 from +0.
 ```
     /* Do the direction calculation */
     az = spheroid_direction(&g1, &g2, spheroid);
     /* Ensure result is positive */
     return az < -0 ? 2*M_PI + az : az;
     // return az;
 ```
