-z option in r.stats

[Olga Fishman]

Hi, I am considering changing the -z option of r.stats to report only
the combinations in which no layers have zero values.

currently the -z option in r.stats only filers out zero from ALL  layers.
If any layer reports a non-zero value, then this combination is reported.

I want to gather some information about what is more usefull and comfortable
for GRASS users. Should I change it or should I leave it as it is now?

Responces are greatly appreciated.

Olga
