No.

svn_fs_copied_from() will only return information about copies when you ask
it of the actual copy target.

svn_fs_history_prev() will traverse history thru copies for any subtree of
the copy.

For example, in our Greek tree, if r2 is a move of '/A' to '/Z', then:

   svn_fs_copied_from('/Z', r2) = '/A', r1

   svn_fs_copied_from('/Z/B/E/alpha', r2) = NULL, SVN_INVALID_REVNUM

but:

   svn_fs_history_prev('/Z', r2) = '/A', r1

   svn_fs_history_prev('/Z/B/E/alpha', r2) = '/A/B/E/alpha', r1
