Subject: Bug in IO#write under windows

If you write line breaks to a file under windows, the write and syswrite 
methods count a line break as one character, not two, meaning that the 
value returned is incorrect.

e.g...

File.open('arr.txt', 'w') do |file|
  arr = [ "123\n", "456" ]
  puts file.write(arr)
end

This bit of code displays the number 7 on the screen.  The actual size 
of the file is 8.  This is causing me problems with File#truncate, 
becuase I'm truncating too much of the file!
