 variables.html says
 {{{
 Use g.gisenv within GRASS. This permanently predefines GRASS variables
 in the $HOME/.grass7/rc file.
 }}}
 Yes, "within". However it should mention that that won't work with --exec.

 Mention with --exec a temporary $GISRC is used:
 {{{
 $ grass /.../TC46 --exec env
 GISRC=/tmp/grass7-jidanni-12382/gisrc
 }}}
