Merge remote tracking branch 'version-control/namespaced' into namespaced

This is a no-op merge, explicitly considering and rejecting the
SVN-specific removal from the subject-level master branch.  This
avoids merge conflicts if an aggregation branch wants to merge both
our namespaced branch and the subject-level namespaced branch.
