Creates revision number N say.

Creates revision number N+1 say.

Since the changes have been committed to the repository, you don't
need a new command to resurrect the directory, you just need the merge
command to support removing deltas as well as adding them. Basically
you tell the merge command to remove the difference between revisions
N and N+1, just as you would for a normal file. That's what version
control is for.

It might be as simple as

$ svn merge --reverse newdir

to reverse the last change. Or more genrally

$ svn merge -r N+1 --reverse newdir
