			     =================

Bash-Release:	5.1
Patch-ID:	bash51-002

Bug-Reported-by:	oguzismailuysal@gmail.com
Bug-Reference-ID:	<CAH7i3LoHFUa4aSF5-AD2r80HG-p-YzD_9ZxomarZkhP8NMq63g@mail.gmail.com>
Bug-Reference-URL:	https://lists.gnu.org/archive/html/bug-bash/2020-12/msg00037.html

Bug-Description:

If there are no jobs, and the `-n' and `-p' options are both supplied to
`wait', bash can assign a value to the variable name specified with `-p'
instead of leaving it unset.

Patch (apply with `patch -p0'):
