Well, frankly I really don't like the idea of using OP_2 just to avoid chan=
ging
some unit tests. We're doing something that many people will use for years =
to
come, that's unnecessarily obscure just because we don't want to spend a bi=
t of
some modifying some tests to pass.

OP_TRUE is the obvious way to do this, and it results with a 1 on the stack,
which plays better with other standardness rules. OP_2 means we *also* may =
need
to special case having a 2 on the stack in certain implementations of other
standardness rules.
