[jdom-interest] Deprecating some XMLOutputter constructors

[guru at stinky.com]

Alex -

Thanks for the writeup.  I'm not sure your algorithm will work any
better than the current one -- that is to say, it will probably have
some cases it handles very well, and others that it can't handle
without a lot of special-case hacking.  Pretty-printing is hard,
mostly because every permutation of document + programmer leads to a
different definition of "pretty" :-)

It's a little late in the game to change the XMLOutputter algorithm
wholesale.  However, if you're inspired, I'd recommend that you make a
subclass of XMLOutputter that implements things your way.  I'm pretty
sure you'd only have to override one method, printElementContent.  If
you do this, please apply the patch I posted recently, which makes
that method's internals easier to understand, or wait a few days,
since I'll be doing some more refactoring to printElementContent that
should make your job easier.

Cheers -
