No, nothing to do with debug messages. I just mentioned that in
reference to rationalizing the debug and verbosity levels, as suggested
earlier on the list (can't find the message now). (min=0, max=5)
I see no real technical need for this many verbosity levels, it's just
to make the controls more consistent & easier to learn.

export GRASS_VERBOSE=2

The problem is in the current setup I find that r.terraflow needs a -v
verbose flag. This is a bit silly as we now have a --verbose flag. But
currently --verbose is no different than without --v. Currently
--verbose only makes the module do something different if you have set
GRASS_VERBOSE=0,1.

By setting MAXVERBOSE to 3, and setting STDVERBOSE to 2, the --verbose
flag will actually make some difference. 
Presently  STDVERBOSE == MAXVERBOSE.


hope that is clearer,
