ああ、そうですね。Telnet#print() は IAC と EOL の処理が行われるという
説明が本当ですね。そして、ここでネーミングの大きな間違いに気づきます。

  Telnet#puts("string")  # == Telnet#print("string\n")

Ruby 的には本当はこうすべきですよね。Telnet#print() の利用率は高いと思
われるので、一気に切替えるのは問題が多発しそうですから、とりあえず
$VERBOSE == true 時に将来的には "\n" を付加しなくなるというワーニング
を出すようにし、Ruby 1.8 ぐらいで移行という感じでしょうか。ドキュメン
トの方はこんな感じでどうでしょう。

=== SEND STRING

  host.print("string")
  host.puts("string")

Telnet#puts() adds "\n" to the last of "string".

WARNING: Telnet#print() NOT adds "\n" to the last of "string", in the future.

If "Telnetmode" option is true, then escape IAC code ("\xFF"). If
"Binmode" option is false, then convert "\n" to EOL(end of line) code.

If "WILL SGA" and "DO BIN", then EOL is CR. If "WILL SGA", then EOL is
CR + NULL. If the other cases, EOL is CR + LF.

その他のドキュメントの修正は取り込ませて頂きます。ありがとうございます。
