Yes, you are right. There is a shit. I was trying something and that output
came up yesterday. Just now I completed r.drain and output looks pretty
r.drain direction map generation code is completely wrong Or is not working
for a long period when I checked trac last update was 3 years ago for
filldir.c which i guess is incomplete
*Anyone got good output recently with r.drain?*
If so please let me know the revision.
Can I continue fixing r.drain?
Because currently its works for -c flag which is by default?
please see new screenshot 
@Margherita Di Leo
Could you provide your data for testing r.drain module directon calculation
feeding points from vector?
