But it will happen. For example, the locking branch has changed the output
of svn update to add an extra column indicating that a lock was broken.

The problem with the current output is that it isn't easy to extend
without breaking scripts. Still, we sometimes need to extend it for enw
functionality.

Or you could go the other way round, writing a filter that reads the XML
and outputs what you actually need. That could be done with XSLT, for
example, so it doesn't need to be a "real program".
