"""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.
TODO: jam 20051215 There are no tests for ftp yet, because we have no ftp server
TODO: jam 20051215 Currently the default behavior for 'bzr branch' is just
defined by the local umask. This isn't terrible, is it
the truly desired behavior?
