Update 01-chapter7.markdown

Global variables are not necessary to demonstrate anything in this script. Tested:

% cat foo.rb
#!/usr/bin/env ruby

refname = ARGV[0]
oldrev  = ARGV[1]
newrev  = ARGV[2]
user    = ENV['USER']

puts "Enforcing Policies... \n(#{refname}) (#{oldrev[0,6]}) (#{newrev[0,6]})"

% ./foo.rb refs/heads/what $(git rev-parse HEAD) $(git rev-parse HEAD~~)
Enforcing Policies...
(refs/heads/what) (27240a) (ae2ef7)
Update command line output in Chapter 2

The command line output in the examples is slightly inconsistent with the
latest version; git doesn't strip content from the commit message.
