[GRASS5] bugreport r.drain (?)

[Markus Neteler]

Hi all,

r.drain seems to accept all types of raster maps now.
(updated in CVS).

Still a problem is that the drain path becomes an area
sometimes.

I would expect:                I regularly get:
(something like this)
 |                                 |
 |                              |##|###
 \                              \##\####
  \                              \##\#
   \---\                           \\\\
        \                            \\
         \                             \

The "thinning" doesn't take place...
I have a small screenshot here (21kb):

The DEM is 12.5m resolution in DCELL (double FP).

Any help or comment is highly appreciated!

Markus
