 As written in the summary. The commands i used:

 r.watershed -a -b elevation=dem threshold=1500 accumulation=accum
 drainage=drainage stream=stream1500

 r.stream.distance stream_rast=stream1500 direction=drainage elevation=dem
 method=downstream difference=elev2stream

 elev2stream map has several null values. I tried with 2 different dems,
 srtm and aster2, on senegal area.

 Linux Fedora 20, GRASS 7.1.svn (r63559)
