justify_line(): Re-add wordlen == 0 test

Browse Source 
This fixes ELinks crashing on this with terminal width e.g. 103:

	<p align="justify">
	xxxx xxxx xxxx xxxxx xxxxxxx xxxxx xxxxx xxxxx xxxxx xxxxx xxxxx xxxxx
	xxxxx xxxx xxxxxxx xxx xxxxxxx xxx xxxx xxxx xxxx xx xxxx x xxx xxxx
	xxxx xx xxxx xxxx xxxx xxx&mdash;xxx xxxx xx&mdash;xxx xxxx<em> </em>x
	xxxx </p>

This test was removed for an unknown reason in commit
