 apparently in raster/r.stats/stats.c update_cell_stats(), but then I get
 lost as I'm not really trained to deal with hash tables.


 Interestingly if I change the resolution to misalign I only get the first
 output step:
 {{{
 G65> g.region rast=elevation.dem
 G65> r.stats elevation.10m nsteps=2 -c
  100%
 1061.064087-1453.903748 294978
 }}}
