stop clipping the last word off short release titles

The release-title derivation word-clipped even when the changelog headline was already under 80 chars: first_line[:80] returned the whole string, then rfind chopped the final word. v0.7.1 shipped as "...add test" instead of "...add test coverage". Only word-clip when the line actually exceeds 80.
