Description

The following script, reported to JRuby in https://github.com/jruby/jruby/issues/2762, shows that MRI does not advance the position of a Tempfile when using copy_stream:

require "stringio"
require "tempfile"
file = Tempfile.new('foo')
IO.copy_stream(StringIO.new('foo'), file)
file.eof? #=> false (it's on the beginning)

Other types of streams leave the destination where it is after the copy, so I believe this is a bug.
