just to report that the warning does not show up in devbr6;
r.univar reports no output besides 100% (it's a bug which comes
from the multi-map support, where it skips over empty maps but
doesn't warn you when none of the input maps contain data);
and the f_range file in cell_misc/ for it is 0 bytes.
