BTW, I found another bug related to BZR_HOME and config_dir.
If BZR_HOME contains path to non-existing directory bzr
generate not very clear error message:

E:\Bazaar\mydev\show-version>set BZR_HOME=non-existing

E:\Bazaar\mydev\show-version>python bzr st
bzr: ERROR: [Errno 2] No such file or directory: 'non-existing/bazaar'

E:\Bazaar\mydev\show-version>python bzr -Derror st
