Subject: [ruby-dev:49380] [Ruby trunk - Bug #11729] String#split(nil)	incorrectly uses $;

Issue #11729 has been updated by Kaneko Yuichiro.


I think this is intended.

Hi,

Is this intentional?

```
$; = "@"
"a@b".split(nil) # => ["a", "b"]
```

I expect `["a@b"]` because I found the following sentence in the Japanese documentation.

```
1 バイトの空白文字 ' ' か nil
先頭と末尾の空白を除いたうえで、空白文字列で分割する。
```
