The libxml-parse-html-region and libxml-parse-xml-region functions both
appear to ignore their discard-comments parameters.

When I enter the following text in a buffer and mark it:

  <p>This <!-- and --> that</p>

Then the result of evaluating the expression

  (libxml-parse-html-region (mark) (point) nil t)

is

  (html nil (body nil (p nil "This " (comment nil " and ") " that")))

and the result of evaluating the expression

  (libxml-parse-xml-region (mark) (point) nil t)

is

  (p nil "This " (comment nil " and ") " that")

In both cases, I would expect that passing t as the fourth argument
would cause the comments to be dropped, but they are not.

Incidentally, I notice that the documentation for
libxml-parse-xml-region includes the following sentence:

  If DISCARD-COMMENTS is non-nil, all HTML comments are discarded.

I imagine this ought to refer to "XML comments" rather than "HTML
comments."
