Bug #835: fix for Documentation on ruby*/lib/benchmark
http://redmine.ruby-lang.org/issues/show/835

Author: Sandor Sz��cs
Status: Open, Priority: Low

The example in the documentation of the module Benchmark is not quite correct, because the constants are not defined.
We have to add "include Benchmark" to get them.
Patch files are attached for ruby 1.8.{6,7} and 1.9.

Context:
[code]
# require 'benchmark'
#
#    n = 50000
#    Benchmark.benchmark(" "*7 + CAPTION, 7, FMTSTR, ">total:", ">avg:") do |x|
#      tf = x.report("for:")   { for i in 1..n; a = "1"; end }
#      tt = x.report("times:") { n.times do   ; a = "1"; end }
#      tu = x.report("upto:")  { 1.upto(n) do ; a = "1"; end }
#      [tf+tt+tu, (tf+tt+tu)/3]
#    end
...
module Benchmark
..
end
[/code]
