Diagonal cells not treated properly with r.reclass.area and minarea

Issue according to Markus Metz:

With method=rmarea, r.reclass converts the raster clumps to vector areas. That single cell in your example below, that either belongs to the larger clump 1 (with -d) or forms a separate clump 2 (without -d) will always be a separate small vector area (topology or not does not matter here) and thus will always be removed independent of the 2-cell clump. The vector approach is thus not working here as expected.

Suggested solution:

1) The "-d" flag should not be valid when "rmarea" option is set.

2) Documentation should be updated to reflect this
