xmltotext_with_options sometimes tries to replace the existing root node of a libxml2 document. In that case xmlDocSetRootElement will unlink and return the old root node; if we fail to free it, it's leaked for the remainder of the session. The amount of memory at stake is not large, a couple hundred bytes per occurrence, but that could still become annoying in heavy usage. Our only other xmlDocSetRootElement call is not at risk because it's working on a just-created document, but let's modify that code too to make it clear that it's dependent on that.
