Bug#298761: quintuple-agent: bash completion for q-client

[Hans Ulrich Niedermann]

Package: quintuple-agent
Version: 1.0.4-4
Severity: wishlist
Tags: patch


Install attached file as /etc/bash_completion.d/quintuple-agent
for q-client bash completion.

It is my first bash completion function, but so far, it works quite well
for me.
