[buildd-tools-devel] Bug#696543: [PATCH] etc: make bash completion work for colon values

[Peter Wu]

Package: schroot
Version: 1.6.4-1
Tags: patch

Patch is based on debian/schroot-1.6.3-1-33-g75634db, but should apply to any 
version (at least 1.3.2-1).

--chroot (and -c) accept values like chroot:foo and session:foo-abc. Standard
bash completion treats colons as whitespace, hence we need a way to force that
off.

Fix based on http://stackoverflow.com/q/10528695/427545 (thanks Radu Gasler!)
