#28 Unnecessary redraws on SIGWINCH
When running TF in screen, SIGWINCH is sent to tf whenever one re-attaches to a running screen. This will trigger tf to redraw the screen. This, in turn, copies the last set of lines in screen's scrollback history, which is unnecessary and can be bothersome.
I couldn't tell whether the redraw was good for anything, so I just disabled it. I left it in place for those who have visual mode turned on though. See applied patch.
