rake/testtask with t.loader = :direct doesn't run out of the box, overescapes

[zenspider]

Given:

Rake::TestTask.new :test do |t|
  t.loader = :direct
  # t.test_files = FileList["./test/test*.rb"]
end

By default rake test wants to run with a pattern:

      @pattern = 'test/test*.rb' if @pattern.nil? && @test_files.nil?

When I run this I get:

...
.../core_ext/kernel_require.rb:54:in `require': cannot load such file -- test/test*.rb (LoadError)
...
Command failed with status (1): [ruby -I"lib" -e "ARGV.each{|f| require f}" "test/test*.rb" ]

Notice the pattern in the command has quotes around it, preventing shell expansion. This is because that last argument is over-quoted by file_list_string:

    def file_list_string
      file_list.collect { |fn| "\"#{fn}\"" }.join(' ')
    end

@zenspider Can you try with master branch?
