fix exiting breakpoint interactive context

Browse source 
Commit 8d27f81a to change how background jobs are handled (killed rather
than left running) when the shell is exited did not correctly handle
the nested interactive context created by the `breakpoint` command. This
fixes that mistake. Now any background jobs that already existed, or were
created within the `breakpoint` context, are left running when exiting
that context.
