Pull up following revision(s) (requested by christos in ticket #1323):
bin/sh/jobs.c: revision 1.74
bin/sh/jobs.c: revision 1.75

Process pending signals while waiting for a job:
$ cat << EOF > hup.sh
#!/bin/sh
trap 'echo SIGHUP; exit 1' 1
sleep 10000 &
wait
EOF
$ chmod +x ./hup.sh
$ ./hup.sh &
$ kill -HUP %1
report the signal that wait was interrupted by, which is not always SIGINT
anymore.
