Comment (by mmetz):

 Replying to [ticket:2981 mankoff]:
 > I'm not sure if this is a bug, but I think so. When I set the
 {{{blocking}} option to {{{r.watershed}}}, I see no difference in the
 accumulation map.

 The `blocking` option only affects RUSLE-related outputs `length_slope`
 and `slope_steepness`. Slope lengths are calculated from drainage paths
 through the terrain. Path tracing stops as soon as a blocking cell or a
 stream cell is encountered.
