PATCH: "sh" job control

[Clint Adams <schizo@xxxxxxxxxx>]

Most other shells seem to default to exiting right away when told to
exit while there are jobs in the job table.  zsh provided no way for
silence (other than disowning all jobs or setopt nomonitor)

The following patch introduces an option "shjobcontrol" (bad name?)
which skips the checkjobs() call.
