It's a long-time wish to add copy-to information to svn log and other
commands. It would enable forward-searching in the directory tree and
with that many usefull applications. For now, it's not possible to
show the information since it's not stored in the repository (which
only stores copy-from). Therefore on larger repositories, it would be
very computational intensive to deduce the required information.

It'll probably be added some day, but for now there were more
important features to add.
