Sorry, didn't mean to make things more difficult than they have to be.
FYI, you can get the delta for a branch which was branched with
changes by diffing its HEAD against the branch it was created from at
the revision it was created from (determined via 'svn log -v').
# Find trunk revnum
svn log -v --stop-on-copy \
http://svn.collab.net/repos/svn/branches/javahl-diff-summarize
# Get delta
svn di http://svn.collab.net/repos/svn/trunk@22588 \
http://svn.collab.net/repos/svn/branches/javahl-diff-summarize@HEAD

It's just conventional (like using the EventListener marker
interface). EventObject is a common marker interface used for events
passed to Java listeners. It's not strictly necessary.
