Mark, I've written the code for the diff summarize JavaHL bindings:

  http://svn.collab.net/repos/svn/branches/javahl-diff-summarize

When you have a moment, I'd appreciate review of at least the Java
APIs. The JUnit test case in BasicTests.java shows how to use it, and
return all diff summaries in a list.

Unfortunately, there's a bug hiding somewhere in my implementation
which I haven't been able to shake out. The bug is triggering an
exception (in native code, I think), which subsequently causes a JVM
segfault when JavaHL's error handling code calls the
env->DescribeException() JNI routine to output a stack trace for the
exception. I've spent quite a bit of time on this bug, and could
really use some extra eyes.
