I received numerous replies to this that suggested using Sequence[ ] 
and/or Level[ ], but the suggestion from  "Barthelet, Luc" <lucb at ea.com>  
that I use

         Line[ Join[{p1, p2, p3, p4}, Table[...,{i,5,20}] ] ]

seems to me cleanest, simplest, "readable", and works fine (at least for 
the purpose I have in mind).
