bug#9265: 24.0.50; libxml-parse-xml-region broken

[David Engster]

Recipe:

* emacs -Q

* Enter the following:

(libxml-parse-xml-region (1- (search-forward "<" nil t))  (point-max))

<?xml version="1.0"?>
<whatever>hi there!</whatever>

* Evaluate the first line.

* Returns nil, but should return '(whatever nil "hi there!")'

* Note that `libxml-parse-html-region' still works fine, though.


I'm pretty sure I could pinpoint this issue to this commit:

  * xml.c (parse_region): If a document contains only comments, return that, 
too.
