You can cd to some directory of course.

post-commit can't touch the wc from which the commit was started, but
you could have another wc which it runs svn up in. However, then you'd
need a way of stopping infinite recursion, and preventing the
ChangeLog update commits from being in the ChangeLog, and use a lock
to prevent races when two post-commits are running simultaneously.
Perhaps you should use svn log, and generate the ChangeLog when you're
packaging the software for distribution? Or output the ChangeLog to
somewhere outside the repo.

Also, though I haven't looked at svn2log, it'd probably be possible to
modify it to work with URLs.
