Now that Lillian and I have good documentation for the ElementBuffer
class
(http://java.sun.com/products/jfc/tsc/articles/text/element_buffer/index.html)
we can finally nail this class down and get it right.
I coded some examples suggested in the document linked above and made
the following change. The examples I coded will be turned into Mauve
tests and committed.

* javax/swing/text/DefaultStyledDocument.java:
(insertUpdate): Removed call to checkForInsertAfterNewline and instead
inlined this method because it needs to change the value of the
finalStartTag and finalStartDirection variables.
(checkForInsertAfterNewline): Removed this method.
(handleInsertAfterNewline): Added case for making the start tag's
direction JoinNextDirection.
