I've checked the latest devel push. I confirmed the new behaviors that
the signaled foreground jobs are immediately notified even in the middle of
trap/bindx/PROMPT_COMMAND, and therefore the `jobs' builtin wouldn't
print the foreground jobs anymore. This would solve a long-standing
issue of my framework about the ambiguous foreground and background
jobs. Thank you.

Also, I confirmed that a=${ (true) }; b=${ jobs; } would not report
the foreground job `(true)'.

Thank you for your consideration and discussion.
