2007-08-23 17:43 AEST by Arthur Barrett - Provide a way to specify default "mode" for files on branches.

eg: 
development branch is -kvx, but "test promotion level" should be -ko.

In particular when a file is added to "dev banch" it should get -kvx, but when 
a changeset is merged onto "promote test" (including added files) it should be -
ko.
