So what should ^^ (or however it turns out) mean, exactly?

I always wanted something like "repository path of current working copy"
- is that what you mean? Maybe ^: could be used as the anchor for
"repository path of current working copy", if you are in a copy of
/some/path/to/project/branch/whatever you might use

  svn cp ^: ^:../../tags/newtag

to copy that path to /some/path/to/project/tags/newtag.

Might be difficult to implement, I suppose but IANAD ;).

Tino.
