Description

http://toro.2ch.net/test/read.cgi/tech/1324826777/666-675 で指摘があったのですが
Windows で IO.foreach や IO.read などで mode を指定せずに binmode:true を指定すると例外が発生するそうです。
（試していません。すみません）

元の書き込みを参考に処理を追うと、rb_io_extract_modeenc で、mode 指定がないときには DEFAULT_TEXTMODE を付与していますが
その処理の後で extract_binmode 呼び出しがあり、FMODE_BINMODE も同時に付与されてしまう、という流れのように見えます。
