Forgot to add: an important difference, of course, is that 'svn' can
only be used to inspect revisions that have already been committed
(like from a post-commit hook, or from tools that run in a cron job
and inspect committed revisions). If you want to inspect an
uncommitted transaction, as you would do in the pre-commit hook, then
you have no alternative, you have to use svnlook.
