Hi,

Ah, and node comparison for non-element nodes was enhanced.
This was needed to speed up sorting of XPath node sets.
See http://bugzilla.gnome.org/show_bug.cgi?id=165547 

Also elimination of needless sort operations for arguments
of count().

There's still a TODO to eliminate other needless sorting, as
e.g. for "foo[ancestor::bar]"; ancestor::bar is currently
sorted, but doesn't need to be.

Regards,

Kasimier
