Wyatt Allen 32fb1d9e2b Allow totally empty lines of diff content
Empty diff lines had been coerced to non-breaking spaces in order to
preserve blank lines when copying to the clipboard [1]. Since then, copy
was upgraded to traverse the diff object rather than the DOM [2],
thereby obviating the need for non-breaking space to preserve blank
lines.

Remove the non-breaking space.
