Small nit in tutorial

[Stephen Waterbury]

In the Bazaar Tutorial
(<http://doc.bazaar-vcs.org/bzr.dev/tutorial.htm>), near the bottom
of the page in the section "Publishing your branch", the rsync
command given:

rsync -avrz LOCALBRANCH servername.com/this/directory/here

contains a redundancy:  "a" implies "r", so "-avz" is sufficient.
