[GRASS-dev] r.flow and G_message

[Jachym Cepicky]

hallo,

i do not know, how to solve fprints in r.flow. 

The module use it's own function to print messages (diag) 

When i removed this function and rewrite everything with help of
G_message, the result is not well-arranged:

r.flow elevin=elevation.dem aspin=aspect barin=roads flout=tmp1
lgout=tmp2 dsout=tmp3 --o

What to do? Should I remove all informations about reading, precomputing
and  allocating for each raster map? I suggest, that the most verbose
output could look like this:

Opening output files...

what would you say?
