#1674: r.cross problems when overlaying layers with no-data
------------------------------+---------------------------------------------

------------------------------+---------------------------------------------
When overlaying two layers that contain large areas of 'no data', r.cross
seems to assign random values to raster cells with no-data, even when
using the -z flag. See for example the output of r.what for a point where
both input layers have no data but the raster cell get's assigned a value
(30114 in the example below):
r.what --v -f -n input=wdpaPNV@ConsStat
coordinates=1549281.412639,-1312241.263941
easting|northing|site_name|wdpaPNV@ConsStat|wdpaPNV@ConsStat_label
1549281.412639|-1312241.263941||30114|no data; no data
Probably because of this problem, r.cross cannot be run on large layers
with large areas of no-data, it just get's stuck
