Subject: [PATCH 5/6] Use unbreakable endash in \clnrefrange{}{}
Using a shortcut macro "\==" instead of a plain endash ("--")
can prevent widowing of the 2nd cross reference.
NOTE:
cleveref's \crefrangeconjunction macro could also be changed as
well to change the behavior of \crefrange and \Crefrange commands.
However, such a change would end up in large under/over fill
where generated cross-references are more than a few characters
long.
