description:
Allow shells forked to run command substitutions while expanding
prompts to exit when they're done, rather than forcing them to
turn into interactive shells and start reading input ...

Completes a part of the previous changes (just 10+ weeks late...)

Should fix the prompt expansion issue reported by Ca?c on
current-users.
