Ah, you're right.  Sorry about the miscommunication.  Elliotte changed
the class to use a Writer internally but the public API lacks a method
that accepts a Writer.  So what do people think of adding output()
methods that accept Writers?  I think it'd be a fine addition, but with
one twist.  I propose we don't provide

output(Document, Writer)

and only provide

output(Document, Writer, String encodingOfWriter)

This is because the top method requires the Writer to be a Writer for
the same encoding that we have as default (UTF-8), or the encoding that
was passed in to the constructor (could be anything).  That seems
awfully risky.  Forcing you to specify will keep people from calling
this in a servlet:

outputter.output(doc, res.getWriter())

It seems perfectly reasonable, but since we default to UTF-8 and
servlets default to Latin-1, you'll have serious problems.  Opinions?
