 * Some xterm terminals (including xterm itself) will send Ctrl+H on hitting the
 * backspace key for backwards compatibility with old Unixes. This archaism
 * breaks terminfo compilance causing backspace to break entirely in nanorl.
 *
 * This behavior can be disabled in the xterm configuration if the user chooses
 * to do so. Meanwhile, this patch fixes backspaces in out-of-the-box xterm.
