Apparent premature approval

[Daniel van Vugt]

If you look at bzr log on lp:mir you might be forgiven for thinking some 
non-trivial branches have landed with approval from only a single person.

This isn't true because it seems people have been top-approving without 
adding comments or regular approvals. So that's OK.

But I guess for the sake of having a nice accurate bzr log, please do a 
regular approval before top-approving.
