Bug#31206: start-stop-daemon --stop --name does not work

[Klaus Weide <kweide@tezcat.com>]

Package: dpkg
Version: 1.4.1

Option --name for start-stop-daemon is documented in the man page and in
the output of start-stop-daemon --help, but does not seem to be
implemented:

# start-stop-daemon --stop --verbose --name something
start-stop-daemon: need at least one of --exec, --pidfile or --user
Try `start-stop-daemon --help' for more information.
# start-stop-daemon --version
start-stop-daemon version 0.4.1, 1997-01-29
