0001454: [Fix] Add vertex handle doesn't work for arrows.
Go to objects. Get an arrow. Add handles.
The triangle does not add a vertex. Huh?
Polygon class ArrowPrototype goes thru pains to make the arrow inflexible. This confuses the users who expect the add vertex triangle to work as normal.

This changeset comments out the old code and reverts to the more usual behavior.

Ideally someone should do a use test to see which way is best for users. Realistically someone should choose whether this is a bug and fix it or not.

Historical notes: the routines affected were changed in sept-oct 2002 by sw.

This changeset is offered to give the maintainers a choice and to give the users who don't like the current behavior a remedy."!

First cs missed the change to PM class>>arrowPrototype.

While either change fixes the behavior, keeping the code clean requires both fixes.
