Code review comment for lp://staging/~nmb/bzr-keywords/after-2.6

Yes, r20 of bzr-keywords broke compatibility with versions of bzr that
don't have r6498.5.1 (merged in r6517):

nmb@garble[~/src/bzr/bzr.all]$ bzr revert -r tag:bzr-2.5.1
[...]
nmb@garble[~/src/bzr/bzr.all]$ ./bzr selftest -s bp.keywords
'module' object has no attribute 'filter_stacks_registry'

OK

This came up on the mailing list recently and reverting to r19 fixed
the problem on bzr 2.5.0.
