OK, I'll try it again.

No, I don't think it will ever be possible for you to do that, for two
reasons:

1.  Subshells don't have job control, so the `jobs' builtin returns nothing

2.  Subshells don't have jobs, for the reasons I stated before, so `jobs'
    wouldn't return anything if job control was on.

I think it would be too messy to make this work for just the `jobs' builtin,
the way the code in execute_cmd.c is structured.  It would require treating
the `jobs' builtin separately from everything else.
