"""Tests for bzr setting permissions.
20
Files in the branch control directory (.bzr or .bzr/branch) should inherit
21
the .bzr directory permissions.
22
So if the directory is group writable, the files and subdirs should be as well.
25
# TODO: jam 20051215 Currently the default behavior for 'bzr branch' is just
26
# defined by the local umask. This isn't terrible, is it
27
# the truly desired behavior?
