The easiest workaround is that we reorder the parameter list. At time we have
rast = 1st = default.

See
http://grass.osgeo.org/grass71/manuals/g.mremove.html

Putting there, say, "label" will enforce the user to have to set rast=
for deleting raster maps. This would require no extra efforts and
minimize the risk except for those using labels (so we could even add
a dummy parameter there. Or select another rather unknown parameter
from that list to become the first in the list).
