"svn unpull"?

Does svn have a command similar to darcs' "unpull"?

That is, if I have a working copy with version 5, I want to put my
working copy in the state it would be in if version 3 had never been
checked in (that is, the changes in versions 1,2,4,5). And next time
I do "svn update" I want to get changeset 3 (since it is still in the
repository).

Right now I just "svn diff" and apply the reverse patch, but I'm
afraid of accidentally committing this modification. And diff/patch
won't handle "unmerging" version 3 from the changes in 4+5 as
intelligently as svn should be able to.

This is really useful when somebody else checks in changes that break
the project and simply undoing those changes in the repository or
fixing the breakage is not an option (for policy/seniority/etc
reasons).

Thanks,
