Fix infloop in redisplay due to truncated lines and invisible text
* src/xdisp.c (forward_to_next_line_start): Don't call 'get_next_display_element' after finding the end of line. This avoids setting the row's end position to the wrong value when the next screen line begins with invisible text; that wrong value caused set_cursor_from_row position the cursor in the wrong screen line, and eventually triggered bug#24109.
