I thought your suggestion was:

    'rebase @{-1}' says 'Fast-fowarded HEAD to @{-1}'. It should say
    'Fast-forwarded HEAD to 4f407407 (rebase: allow "-" short-hand
    for the previous branch, 2014-03-19)' instead.

Or it could be:

    'rebase @{-1}' says 'Fast-fowarded HEAD to @{-1}'. It should say
    'Fast-forwarded HEAD to master' instead.

In either case, it does not look like such a change is about
teaching "-" as a synonym to "@{-1}".
