Right. Sometimes you fall back to the old svndiff format because
backwards-compatibility fails. This isn't the end of the world.
I expect that, even in XML documents with CDATA sections, the number of
changes which include the ]]> string will be small.

Basically, you give up backwards compatibility in some limited and
well-understood circumstances, but for the vast majority of cases you get
the best of both worlds. I think this is an acceptable tradeoff.

(And remember, you need only lose backwards-compatibilty *on the chunk
with the offending string*. Most of the patch will still be
