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.
