Well my point is, that I always will report the revisions
in descending order (in constrast to the command line
interface). The problem is that forward-following the copy
"history" will create a tree of paths to follow.

O.k. I will allow HEAD, BASE, WORKING, revNum for any of
the three revision parameters. This is not a problem as
long as there is only one path to handle.

Again, the copy forward-following is the problem. Therefore,
"svn log path@1 -r4:3" may be ambiguous. What will actually
be returned is equivalent to "svn log path@4 -r4:3".

Of course, "svn log path@5 -r4:3" will follow all renames of
"path" until revision 4 is found.

You are right in that I have access to all information
required to traverse changes to and fro. In future, it may
be possible to follow all copy destinations at once (part
of that code is already available: the batch iterators).
