---- Subject: r.neighbors: add null pass-through support
...
r.neighbors should have an option so output maps only contain data
where data exists in the original map.Currently output maps 'grow' to the search distance, i.e.
output_val=mean(nonNULL(cell_values))
I should have mentioned, the reason this is needed is that r.neighbors
doesn't respect a null MASK when writing the output file, perhaps that
is the real bug.

The mask only applies to input, not output.
