Remove revisions?
Is it possible to remove the last revision (or last n revisions) from a
repository?
I don't see anything that describes how to do this with either the svn
or the svnadmin command. I wouldn't expect it in svn but I would think
that svnadmin would have the ability to remove revisions. Conceptually,
it seems easy to do.

Given the current state, how would I do either of the following?
- Save an older revision to the head.
- Move the last n revisions to a branch.
I suspect that the first is easier but the second would be a better
solution.
I tried checking out the desired version and committing it but svn found
no differences so nothing was committed.
On a semi-related note, the man page says
-n or --dry-run Don't actually do it, only show what would be
done if the given command did run.
but when I try
bash> svn commit --dry-run
svn: invalid option: --dry-run
[...]
bash> svn commit -n
Error: subcommand 'commit' doesn't accept option '-n [--nonrecursive]'
[...]
The man page appears to be out of date or 'svn commit' appears to be
missing the --dry-run option.

Actually, removing the most recent N revisions is much easier than
"svn obliterate", because earlier revisions cannot possibly have
dependencies on later ones. A correct but inefficient approach would
be simply to delete those rowse from the `revisions' table; nicer
would be to remove the corresponding stuff from `nodes' and `strings'.
Of course, working copies would be invalid, but detectably so -- at
least until new revisions using the same numbers are committed.
