Subject: [ruby-core:77449] [Ruby trunk Bug#12793] Warning.warn with	non-string object

Issue #12793 has been updated by Kazuhiro NISHIYAMA.


`Kernel#warn` accepts `nil` and `1`, but `Warning.warn` raises `TypeError`.
Is this difference expected?

```
% ruby -ve 'warn nil; Warning.warn nil'
ruby 2.4.0dev (2016-09-28 trunk 56281) [x86_64-linux]

-e:1:in `warn': wrong argument type nil (expected String) (TypeError)
        from -e:1:in `<main>'
% ruby -ve 'warn 1; Warning.warn 1'
ruby 2.4.0dev (2016-09-28 trunk 56281) [x86_64-linux]
1
-e:1:in `warn': wrong argument type Integer (expected String) (TypeError)
        from -e:1:in `<main>'
```
