[GRASS-dev] Quiet module output

I agree, --quiet set GRASS_VERBOSE to 0.
But this is not always inherited. Eg. in one of my python scripts I
use the GRASS-Numpy interface
My script is very similar to the example in the wiki, where I use
".read()" to get GRASS maps
into numpy and ".write()" to get numpy arrays to GRASS.
And here the ".write()" uses actually r.bin.in to write the file back
For this process the progress message (...100%) is shown still although the
flag "quiet" is set for the entire script. Looking at the debugging output when
running the script I see that 1) the ".read()" uses r.out.bin --q but
uses r.in.bin --v. So is that setting respectively the definition
of ".write()" with the verbose-flag interfering?
Anybody an idea how to fix that, so that the GRASS_VERBOSE variable
is also inherited to .write() commands in a python.script?
