* xpath.c: Enabled the compound traversal again; I added a
  check to use this only if the have an expression starting
  with the document node; so in the case of "//foo", we
  already know at compilation-time, that there will be only
  1 initial context node. Added the rewrite also to
  xmlXPathEvalExpr().
