pull-lp-source doesn't notify you where package VCS is maintained

[Corey Bryant]

apt-get source gives some nice feedback to show where a package is maintained in a VCS. It would be nice if pull-lp-source did the same.

Status changed to 'Confirmed' because the bug affects multiple users.

This has created issues where people have uploaded a new version of the package, but not known to update bzr branch.
