That was the needed clue.  The problem is that list_pipe_job is wrong
following the return from source().  The complications are that (1)
list_pipe_job is static to exec.c whereas source() is in init.c, and
(2) when I tried exporting list_pipe_job so it could be saved/restored
in source(), it fixed this issue but caused the test for "status of
recently exited background jobs is recorded" to fail (which confuses
me, because I can't see any reason source() would get involved in that

Perhaps source() should be using execsave()/execrestore() instead of
the stack of local copies of the job state globals that it maintains?
