A pre- or post-commit hook should be able to use the Subversion APIs
svn_fs_compare_ids() or svn_fs_check_related() in conjunction with the
values returned by svn_fs_node_id() to answer relationship questions like
this today.

/** Get the id of a node.
 * Set @a *id_p to the node revision ID of @a path in @a root, allocated in
 * @a pool.
 * If @a root is the root of a transaction, keep in mind that other
 * changes to the transaction can change which node @a path refers to,
 * and even whether the path exists at all.
svn_error_t *svn_fs_node_id(const svn_fs_id_t **id_p,
                            svn_fs_root_t *root,
                            const char *path,
                            apr_pool_t *pool);

/** Return -1, 0, or 1 if node revisions @a a and @a b are unrelated,
 * equivalent, or otherwise related (respectively).
int svn_fs_compare_ids(const svn_fs_id_t *a, const svn_fs_id_t *b);
