Comment (by martinl):

 Environmental variables are loaded by load_env()
 source:grass/trunk/lib/init/grass.py?rev=65585#L1710 from default config
 file source:grass/trunk/lib/init/grass.py?rev=65585#L1220. In my case on
 Linux (using Bash), it's `~/.grass7/bashrc`. Eg.

 {{{
 $ cat ~/.grass7/bashrc
 export GRASS_MESSAGE_FORMAT=plain
 $ GRASS_DEBUG=ON ./bin.x86_64-pc-linux-gnu/grass75 -text
 ...
 DEBUG: Environmental variable set GRASS_MESSAGE_FORMAT=plain
 > env | grep MESSAGE
 GRASS_MESSAGE_FORMAT=plain
 }}}

 r65585 has been introduced to read only alias and other commands since
 environmental variable should be already read.
