Line rebreaking on terminal resize

[GoogleCodeExporter]

It would be rather nifty if long lines could be rebroken after the number
of terminal columns changes, much like you see with flowing text in a web
browser. Apple's Terminal.app does this.

This would also solve the problem of window contents disappearing when
increasing the font size in a window that can't be enlarged.

(Fullscreen apps such as editors usually already do this via the SIGWINCH
signal, so this primarily concerns plain command line output and the
scrollback.)
