Re: nested bash 5 interactive sessions without job control

[Grisha Levit]

Looks like the controlling process group isn't being reset correctly
after the "inner" bash exits:

$ trap 'echo "$(ps -o pid,tpgid -p $$)"' EXIT
$ echo $$
54581
$ set +m
$ $BASH --norc -i -c 'set +m; echo $$'
54583
$
exit
  PID TPGID
54581 54583
