Applied at [master bc6ade404b8e530f823c] and [master a7d2e690ae3a701bfbb4].

ant test & ant spec pass. The script at gist from the original reporter works for me.

String#toutf8 defined in kconv module invokes NKF.nkf. NKF.nkf seems to handle only the first chunk of MIME-encoded string.

See 'error' and 'expects' below.

NKF.nkfが内部で呼ばれるが、デコード途中で文字列が切れてしまうパターン
