Comment (by wenzeslaus):

 Using `--exec bash`, this starts to be almost all right:

 Input:

 {{{
 $ grass79 --tmp-location XY --exec bash <<EOF
 g.region -g
 g.proj -g
 EOF
 }}}

 Output:

 {{{
 Starting GRASS GIS...
 Creating new GRASS GIS location <tmploc>...
 Cleaning up temporary files...
 Executing <bash> ...
 projection=0
 zone=0
 n=1
 s=0
 w=0
 e=1
 nsres=1
 ewres=1
 rows=1
 cols=1
 cells=1
 name=xy_location_unprojected
 Execution of <bash> finished.
 Cleaning up temporary files...
 }}}

 With redirecting stdout to a file:

 {{{
 $ grass79 --tmp-location XY --exec bash > test.txt <<EOF
 g.region -g
 g.proj -g
 EOF
 }}}

 Output:

 {{{
 Starting GRASS GIS...
 Cleaning up temporary files...
 Executing <bash> ...
 Execution of <bash> finished.
 Cleaning up temporary files...
 }}}

 File content:

 {{{
 projection=0
 zone=0
 n=1
 s=0
 w=0
 e=1
 nsres=1
 ewres=1
 rows=1
 cols=1
 cells=1
 name=xy_location_unprojected
 }}}
