Subject: Bug#660838: pbuilder: Add complete bash_autocompletion for all flags
 and arguments

Package: pbuilder
Version: 0.206
Severity: normal
Tags: patch

Currently, pbuidler only supports bash_completion for the commands (first argument) and filename completion for the .dsc file.

This patch adds additional support for all flags and filename/directory completion for flags that require this.

The patch is submitted (and accepted) to Ubuntu in two phases, see these bug reports:
- https://bugs.launchpad.net/ubuntu/+source/pbuilder/+bug/770529
- https://bugs.launchpad.net/ubuntu/+source/pbuilder/+bug/933339

Please consider to apply this patch.
Thanks in advance,
  Maarten
