[GRASS-dev] gis.m/d.m don't background on OSX

The recent change to init.sh to not explicitly background doesn't appear to work on OSX (X11 build).

if [ "$osxaqua" ] ; then
  "$GISBASE/scripts/gis.m" | sh &
else
  "$GISBASE/scripts/gis.m"
fi

An Aqua build still explicitly backgrounds, but not an X11 build. And the backgrounding within gis.m/d.m doesn't happen.

And the backgrounding within gis.m/d.m doesn't happen.

I made that change as the d.m and gis.m scripts background themselves:

gui/tcltk/gis.m/gis.m:
-----------------------
[...]
if [ $# -eq 0 ] ; then
        if [ "$HOSTTYPE" = "macintosh" -o "$HOSTTYPE" = "powermac" -o "$HOSTTYPE" = "powerpc" -o "$HOSTTYPE" = "intel-pc" ] ; then
                exec "$GRASS_WISH" $GISBASE/etc/gm/gm.tcl -name gm_tcl
        else
                exec "$GRASS_WISH" $GISBASE/etc/gm/gm.tcl -name gm_tcl &
        fi
        exit
fi

if [ "$1" != "@ARGS_PARSED@" ] ; then
  exec g.parser "$0" "$@"
fi

exec "$GRASS_WISH" "$GISBASE/etc/gm/gm.tcl" -name gm_tcl "$GIS_OPT_GRC" sh &

-----------------------

gui/tcltk/d.m/d.m is much the same.

before randomly adding "&" back in, I'd like to understand why it fails.
These platform tests seems slighly messy to me.

But according to the logic there, it doesn't explicitly background on OSX ("macintosh", "powermac", "powerpc"). And apparently exec doesn't automatically background on OS X (the problem I noticed).

So maybe now the Mac exceptions in gis.m/d.m should be removed?
