Description

I noticed this while working on some custom library code to implement '!~'

Patch to add this to RubySpec, which currently fails in JRuby 1.6.7: https://github.com/jruby/rubyspec/pull/2

irb session showing the failure:

% JRUBY_OPTS=--1.9 irb                      
>> JRUBY_VERSION + " " +  JRUBY_REVISION
=> "1.6.7 3e82bc8"
>> class Foo; def !~(val); return val; end; end
=> nil
>> Foo.new.send(:"!~", /bar/)
=> /bar/
>> Foo.new !~ /bar/
=> true

In the above example, 'Foo.new !~ /bar/' should have returned /bar/, not true.
