Subject: [PATCH] get rid of residual escape codes after skipping shell
 commands

Some applications (e.g. vim) seem to leave behind escape codes in the
terminal after quitting. For some terminals (including xterm and
gnome-terminal) this is somehow interpreted as key strokes by lf. This
is a temporary fix to get rid of these escape codes by restarting
termbox until we can find a proper way to handle this.
