attachment:univar.diff​ prints a warning

WARNING: Unable to get statistics for raster map <terra_lst_day20020206@modis2002lst_1>

Actually commands fail when the map contains no data:

r.info terra_lst_day20020206
...
|   Range of data:    min = -nan  max = -nan                                 |
...

->

r.univar terra_lst_day20020206 --q

no output printed. It should fail or better to print 'nan' values.

Replying to martinl:

r.univar terra_lst_day20020206 --q

no output printed. It should fail or better to print 'nan' values.

The issue is in r.univar, stats.c line 123. However, not that easy to fix since sometimes zones are consideres, sometimes not.

For the record, patch was included in r59916. So the original bug is fixed.
