 Yup, works great now.

 Great, I had just stumbled upon that while testing !

 Now, one more issue: since recently (r57999), there is the possibility to
 abbreviate option values, but this does not seem to work here:


 {{{
 v.rast.stats blks raster=elevation column=elev
 method=mini,maxi,mean,stddev -c
 Processing data (2535 categories)...
 Traceback (most recent call last):
   File "/data/home/mlennert/SRC/GRASS/grass_trunk/dist.x86_64-unknown-
 linux-gnu/scripts/v.rast.stats", line 295, in <module>
     main()
   File "/data/home/mlennert/SRC/GRASS/grass_trunk/dist.x86_64-unknown-
 linux-gnu/scripts/v.rast.stats", line 261, in main
     i = variables[variable]
 KeyError: 'mini'
 }}}

 I don't know exactly what's needed to make this work, but it would be nice
 if it did.
