Code review comment for lp:~rockstar/launchpad/pedantry-round3

Hi there-

  This branch fixes bug #442386 - Junk branches don't support merge proposals.
The idea is that if you need to use merge proposals, create a project. Since
they don't support merge proposals, the "Branch Merges" section is no longer
shown on junk branches. This was just an oversight in the 3.0 conversion and
should have been taken care of a long time ago.

Cheers,
Paul
