Actually, I'm torn on this. It looks really odd to check for !$tree
here, but it's the only supported case where $root shouldn't be defined.
Maybe (!defined $root) is a better test? (Sorry, I did a double-take on
this after I sent it.)
Both would be equally correct, but I suppose the latter would be
clearer. I'll send v2.
