I attempted to reproduce this in a different terminal, in case that was the issue (I originally used Konsole), in this case xterm. I was not able to reproduce under the standard resolution of 80x24. However, by increasing the resolution by fullscreening it (resulting in a terminal size of 212x78), I was able to once again reproducue the bug. Further testing shows that, with that particular file, I am able to reproduce the issue in 116x24 but not 80x24. I am guessing that text wrapping is involved in some way, but I can't consistently figure out where the bug reproduces and when it doesn't (aside from it always or never reproducing under the same terminal size).
