  Well the goal is more to get people to use xmlSave* than the old
xmlNodeDump and htmlNodeDump ones. Options are set at contect creation,
we can add more options and trying to keep the old functions to support the
same would require way too many entry points.

  Hum, sorry, clearly an oversight, I wanted to make xmlsave routines
HTML aware, which in itself  sounds a good idea, no ?
I guess we can use an xmlSave option to force the output to use the
HTML parser or the XML one and then make sure xmlNodeDump* and
htmlNodeDump* use them appropriately.

  Sorry for the breakage, I forgot the old xmlSave* had been remapped to
the new ones.
