CVS commit: src/bin/sh

["Robert Elz" <kre%netbsd.org@localhost>]

Module Name:    src
Committed By:   kre
Date:           Sun Sep 12 01:30:41 UTC 2021

Modified Files:
        src/bin/sh: jobs.c sh.1

Log Message:
Don't dereference NULL on "jobs -Z" (with no title given), instead
do setproctitle(NULL) (which is not the same thing at all).  Do the
same with jobs -Z '' as setting the title to "sh: " isn't useful.

Improve the way this is documented, and note that it is only done
this way because zsh did it first (ie: pass on the balme, doing this
in the jobs command is simply absurd.)
