9.0 beta 3 pgbench -- documentation issue

Greg,

Your current documentation examples for customs scripts in pgbench
includes the variable :scale, i.e.:

\set nbranches :scale
\set ntellers 10 * :scale
\set naccounts 100000 * :scale

However, in the documentation the variable :scale is never set,
resulting in it defaulting to 1.  The example script needs to start with:

\set scale 10
