Right now we're adding new lines after the decl, after the doctype, and
after the last node.  We do this always.  This is because when build
with a SAX parser JDOM is not told about whitespace outside the root
element, nor could JDOM hold the whitespace in its object model, so
without those new lines the output would have no whitespace outside the
root, and that's not how most people write their documents.

Having setNewlines() trigger the newlines is insufficient because for
round tripping you want to preserve the same whitespace in the file. 
You don't want to add new lines in the root to get newlines outside the
root.

It may be appropriate to have another set method that could turn off the
extra newlines.
