FYI: New Leaf/Branch Element tests

["Roman Kennke" <roman dot kennke at aicas dot com>]

I added new tests for the Branch/LeafElements getStartOffset() methods.

2006-02-28  Roman Kennke  <kennke@aicas.com>

        *
gnu/testlet/javax/swing/AbstractDocument/BranchElement/getStartOffset.java:
        New test.
        *
gnu/testlet/javax/swing/AbstractDocument/LeafElement/getStartOffset.java:
        New test.
