kconfig/lxdialog: handle newline characters in print_autowrap()
When exiting menuconfig with unsaved changes, a dialog like the following is shown: Do you wish to save your new configuration ? <ESC><ESC> to continue. The author of the dialog text specified a newline after the '?', and probably expected it to be processed, so let print_autowrap() handle newlines propperly. Also, reword that dialog's second phrase with a real sentence. Signed-off-by: Dirk Gouders <dirk@gouders.net> Tested-by: "Yann E. MORIN" <yann.morin.1998@free.fr> Reviewed-by: "Yann E.
