Prevent long subjects in reviews causing spurious blank lines

If the last field of the review being listed exceeds the width of the
console, then using whitespace padding will result in sufficient spacing
being added to all other line that will appear as spurious blank lines
if they were otherwise less than the console width.

Instead of:

 1234  master  <subject>

 5678  master  <really-long-subject-that-
 wraps-to-next-line>

Display:

 1234  master  <subject>
 5678  master  <really-long-subject-that-
 wraps-to-next-line>
