ENVIRONMENT: bash 1.01 or 1.02 on an HP300 running MORE/BSD4.3
(although I believe it applies to any system).

SYMPTOM: try the following:
------------------------
bash$ unset auto_resume
bash$ cat
^Z
[1]+ Stopped       cat
bash$ cat
^Z
[2]+ Stopped       cat
bash$ jobs
[1]- Stopped       cat
[2]+ Stopped       cat
bash$ kill -KILL %2
[2]+ Killed        cat     [ aww, poor pussy :-) ]
bash$ jobs
[1]- Stopped       cat
bash$ fg
No such job
bash$
-----------------------

BUG: the shell's notion of previous and current job is not always reset when
the current or previous job dies.

FIX: save them.  I think the delete_job function is the right place to
do it; I haven't properly checked when cleanup_dead_jobs, but the
following patch to version 1.02's jobs.c appears to work in the above
environment.
