[Patch] Bug 652766 - Output should not include extraneous newlines when indent is off

I'm not sure what the process is for getting a patch reviewed and
merged, so thought I'd try a quick email to this list as well as
posting it to the bug tracker:
https://bugzilla.gnome.org/show_bug.cgi?id=652766

The output from xsltSaveResultTo currently adds extra newlines at the
root even when indent="off". The patch attached to the ticket makes
these conditional, matching behaviour of xmlSaveOption XML_SAVE_FORMAT
off.
