----------------------------------------
On Windows, if the first argument to File.expand_path is a drive-current path, and the dir argument is relative, you get a bogus result:

~~~ruby
irb(main):001:0> File.expand_path("c:foo", "bar")
=> "C:/Users/djberge/Repositories/bar/c:foo"
~~~

Compare that with Ruby 1.8:

~~~ruby
irb(main):002:0> RUBY_VERSION
=> "1.8.7"
irb(main):003:0> File.expand_path('c:foo', "bar")
=> "C:/Users/djberge/Repositories/bar/foo"
~~~
