    move-lines: simplify a condition and remove dead code
    
    gtk_text_iter_get_line() can never be equal to
    gtk_text_buffer_get_line_count(), it was dead code.
    
    start is always at line offset 0, so we can use
    gtk_text_iter_is_start(), to have symmetric code with
    gtk_text_iter_is_end().
