From emacs -Q evaluate the following and notice that they are different.


(with-temp-buffer
  (insert "\n <test>\n <bob/>\n</test>")
  (xml-mode)
  (indent-region (point-min) (point-max))
  (buffer-substring-no-properties (point-min) (point-max)))

(with-temp-buffer
  (insert "\n<test>\n <bob/>\n</test>")
  (xml-mode)
  (indent-region (point-min) (point-max))
  (buffer-substring-no-properties (point-min) (point-max)))


As best as I could determine it has to do with the prolog being parsed,
then deleted, but not being reparsed.  Thus it thinks <test> is
part of the prolog.  Unfortunately, the code is rather more than I have
time to understand at the moment.
