variables.html: mention not to expect --exec g.gisenv to work

Description

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

Replying to jidanni:

variables.html says

Use g.gisenv within GRASS. This permanently predefines GRASS variables
in the $HOME/.grass7/rc file.

... after the current GRASS session is closed. Note that within a GRASS session, a temporary copy of this rc file is used.

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

Works for me: after closing the GRASS session, or after grass --exec the $HOME/.grass7/rc file is updated accordingly.

OK I see somebody has now noted this in https://github.com/OSGeo/grass/blob/master/lib/init/variables.html

I now made https://github.com/OSGeo/grass/pull/232 to mention it also in g.gisenv.

However in both files, we are now mentioning "after the current GRASS session is closed", but users also wonder "what about the current session?"
