Suggestions from Werner Heuser <werner.heuser@web.de>

- `printlinks' is a great help, but I would like some links not
  to be touched, e.g. some graphics.

- please include a download URL into the source. Imagine somebody
  likes the program and wants to come back and get the current
  version


Proprietary extensions: Microsoft Internet Explorer accepts a
proprietary extension to HTML that looks like malformed mark-up:
"<![if xxx]>" or "<![endif]>" (where xxx is text that doesn't contain
"]"). The parser currently reports (correctly) a syntax error. Should
there be a mode in which this is accepted? If so, as what? as TEXT?


Let hxindex recognize DATA-INDEX attributes in addition to TITLE? 
(These new DATA- attributes are suggested by HTML5.)

Let hxindex look at locale for sorting order?
