I like this one as it is obvious as to it being different (options first)
plus it very much matches the "usual" svn command line order.

Anyway, the point is that a) you'd be able to detect the new format using

Actually, no tomatoes but a nice, large apple :-) To me, at least, this
would allow for backwards compatibility with older externals. The only
issue left is what this does to older clients. If it fails "cleanly" (no
pollution of the WC) then that is reasonable. I guess that it requires some
testing to validate that.
