"""Tests for bzr setting permissions.
Files which are created underneath .bzr/ should inherit its permissions.
So if the directory is group writable, the files and subdirs should be as well.
In the future, when we have Repository/Branch/Checkout information, the
permissions should be inherited individually, rather than all be the same.
