Subject: [ruby-dev:36045] [Bug #516] REXML::Text#wrapは空白が含まれない場合を想定していない

Bug #516: REXML::Text#wrapは空白が含まれない場合を想定していない
http://redmine.ruby-lang.org/issues/show/516

起票者: Sakuro OZAWA
ステータス: Open, 優先度: Normal

空白が含まれない string に対して place = string.rindex(' ', width) とすると nil が返るところ、
これをチェックせずそのまま分割位置に利用しています。
