The XPath bug fix is really ugly and inefficient, but I spent two days hacking
at it and this was the best I could come up with.

The SAX2 listener fixes had to do with crashes in certain conditions, like when
there was a carriage return at the end of a document

Several people submitted patches for the speed regression; it is embarrassing
how long it took me to get around to looking at this.  To this day, I don't
know where the offending code came from.

Encoding fixes

Added a contributed word wrapping option for text formatting.  Devin Bayer
contributed this.  Here's his comment:
"Setting :wordwrapping to :all, wordwraps all text nodes longer than 60
  characters.
  Setting :indentstyle to aString, make aString used as indentation,
  instead of the default '  '.
  And as long as :respect_whitespace isn't set for the element,
  multiline text nodes will be indented."
