Subject: [PATCH 9/13] kconfig/lxdialog: clear long menu lines

From: Sam Ravnborg <sam@...tun.ravnborg.org>

Menulines that were wider than the available
line width is now properly null terminated.

While at it renamed the variable choice => line_y
so it better reflect the usage in do_print_item().
