Should d.m set GRASS_MESSAGE_FORMAT=gui? and if so, should it pop up a

right now it dumps to the term that started d.m:

[...]
GRASS_INFO_PERCENT: 78
GRASS_INFO_PERCENT: 81
GRASS_INFO_PERCENT: 84
GRASS_INFO_PERCENT: 87
GRASS_INFO_PERCENT: 90
GRASS_INFO_PERCENT: 93
GRASS_INFO_PERCENT: 96
GRASS_INFO_PERCENT: 99
GRASS_INFO_PERCENT: 100
