Comment (by wenzeslaus):

I've executed tests with `GRASS_COMPRESS_NULLS=1` and they worked well.
Here is what I was running:

{{{
export GRASS_COMPRESS_NULLS=1
grass71 /grassdata/nc_basic/user1/ --exec python -m grass.gunittest.main
--location nc_basic --location-type nc
export GRASS_INT_ZLIB=0
grass71 /grassdata/nc_basic/user1/ --exec python -m grass.gunittest.main
...
}}}

However, I think that our test coverage is quite low for this especially
for the usage of NULLs.
