commit 5faa0a6b41cf99c0675101d3702a48a81650a936
from: Marcel Rodrigues <marcelgmr@gmail.com>
date: Sun Jun 14 16:37:19 2015 UTC

Remove wrap-around behavior from 'j' & 'k'.

That behavior provided a way to easily move between the top and
bottom of listing. However, this is no longer needed due to the
recent addition of 'g' & 'G'. The new behavior is also more similar
to what we are used to in other programs.
