Bug #13198: Tempfile#size is nil when nothing is written, expected 0

~~~ ruby
require 'tempfile'

tmp = Tempfile.new
tmp.write ''
tmp.close
tmp.size # => nil

File.size(tmp.path) # => 0
~~~

I'm not sure if this is actually a bug, but this behavior really surprised me. I think it would be better to return 0 in this scenario instead of nil, which would match the behavior of File.
