+  If one (or both) of the trees has no branch length, it is possible to
+  specify a value of 'position' to graft 'y' below the node of 'x'
+  specified by 'where'. In this case, the exact value of 'position' is

+  multichotomous if 'y' has no root edge. This can be solved by giving

+  1}): it will be deleted during the binding operation.
