[GRASS-user] SRTM r.watershed at multiple scales

last year you asked me whether the r.watershed output is not aligned to 
the r.water.outlet output in GRASS7 (s.b.). Ie. it leaves small areas 
out. Back then, I wasnt using GRASS7, but I can confirm now that it 
still does it and it is still rather annoying. Have you ever heard of 
the reasons or attempted to fix this?
