not get included in a complete watershed.

Component: Docs | Version: 7.0.0
Keywords: r.watershed, basin, doc | CPU: All
Platform: All |
-------------------------------------+-------------------------
In the current online r.watershed module's help documentation, there is a
conflicting statement to the output generated for the basin parameter.

[http://grass.osgeo.org/grass71/manuals/r.watershed.html\]

In the text it says, "0 values indicate that the cell is not part of a
complete watershed basin in the current geographic region."

If I run r.watershed on the Elevation sample data and set the threshold to
10000, the output basin will have areas on the edges that do not generate
a basin. The values of these areas are null instead of 0 like the
documentation makes it sounds like it should get. It makes sense for the
values to be null instead of 0 so the documentation needs to be updated.
