This fixes the first two cases, but the last case (_3, _3, _3) is still odd:

bbind (print,_3,_3,_3) (1,2,3) --> 3  3  3
bbind (print,_3,_3) (1,2,3) --> table table; should be 3  3?
bbind (print,_3) (1,2,3) --> table; should be 3?

It seems that placeholder _N can only be used if there are at least N
placeholders.
