I just realized that r.mfiler also outputs 0 instead
All r.thin, r.digit (r.in.poly), r.mfiler seem to use unusual
write routines (or not?). At least I am not very sure how
zero shall be treated. In general 0 should be supported.
Maybe my above changes switched that off for r.thin and r.digit?
r.mfiler is untouched so far.
I am clueless here,
