[pulseaudio-discuss] [PATCH] build: Add bash completion

Wed Jan 30 10:11:43 PST 2013
This patch adds bash completion for pulseaudio and all of the utilities.
Channel maps and properties are not yet completed.
This should make mostly pactl/pacmd more useful for bash users.
Thanks to Denis Kasak for the awk magic (fetching ports and profiles
from the card info).
