By all means, but it's a bug in Windows, not Ruby.

Printers require both \r and \n to go to a new line.  DOS decided that
instead of converting output to the printer, text files should be stored
with \r\n, but when read or written to, these should be converted to
\n.  Naturally, this braindead design screws up the file position. 
Linux doesn't do this at all, and Macs only use \r, IIRC.

To get around this, open the file in binary mode (by including b in the
mode string).  Note that you will then need to give text files a \r\n
separator, or Notepad will barf.  (Wordpad can handle normal files,
though.)
