     Type:  defect           |     Status:  new
 Priority:  normal           |  Milestone:  7.2.2
Component:  Raster           |    Version:  svn-trunk
 Keywords:  viewshed, units  |        CPU:  All
 Platform:  All              |
-----------------------------+-------------------------
 r.viewshed manual says that max_distance option is entered in map units,
 but in fact, the value is compared to the return value of
 [https://grass.osgeo.org/programming7/gis_2distance_8c.html#afcaf2970186c47956fa768bf0fac404e
 G_distance], which is always in meters.

 So either we change the manual (simple, no change for the user), or we
 change the code (simple, but changes behavior).
