Code review comment for lp:~michael.nelson/launchpad/652838-select-diffs-for-syncing

The behaviour is nice. Buttons should be in title case (except for subordinating conjunctions and commonly used prepositions):
    Sync selected %s versions into => Sync Selected %s Versions into %s

This may look odd since the interpolated names may not be title case, but the user did that, not us.
