Bug#1081268: shell completion is out-of-date

[VA]

Package: pulseaudio-utils
Version: 16.1+dfsg1-5.1

Debian's pactl supports "get-sink-volume" subcommand:

% pactl help | grep 'get-.*sink.*volume'
pactl [options] get-(sink|source)-volume NAME|#N

and this subcommand is listed in shell completion upstream:
https://github.com/pulseaudio/pulseaudio/blob/master/shell-completion/zsh/_pulseaudio#L269

but not in debian autocompletion, which is therefore obsolete

% grep get-sink-volume /usr/share/zsh/vendor-completions/_pulseaudio
%
