No. It means forcing the original signal disposition to SIG_DFL for the
tty-generated job control signals when the shell is interactive:
/* Called once in a parent process. */
void
get_original_tty_job_signals ()
{
static int fetched = 0;
if (fetched == 0)
{
if (interactive_shell)
{
set_original_signal (SIGTSTP, SIG_DFL);
set_original_signal (SIGTTIN, SIG_DFL);
set_original_signal (SIGTTOU, SIG_DFL);
}
else
{
get_original_signal (SIGTSTP);
get_original_signal (SIGTTIN);
get_original_signal (SIGTTOU);
}
fetched = 1;
}
}
You can use your change, if it works for you, but it just reverts the
bug the bash-4.4 change fixes.
