* Merge from debian unstable. Remaining changes: - etckeeper.conf, debian/control: default to bzr. - debian/cron.daily: Avoid cron emails with daily autocommits if VCS=hg - commit.d/50vcs-commit: Do not use author so that bzr log --line shows the right name (and hostname) - etckeeper: Set HOME=~root if VCS=bzr, so that bzr doesn't create root-owned .bazaar and .bzr.log in home directories when run under sudo * etckeeper.spec: Change version to match Ubuntu version
