The references in this SEE ALSO section are in a non-standard format.
A reference should be a word followed by the section name in parentheses.
So these man pages should write references in the format

Of course, you can get what you want with the following patch:

But it will also highlight every word in those SEE ALSO sections
that have lengthy text in several paragraphs.  Look for example
`M-x man XML::Twig RET' - there are 60 lines in the SEE ALSO section
where all words will be highlighted as a reference!
