には「引数を省略した呼び出し時に $! が nil でなければその例外の メッセージを標準エラー出力 $stderr に出力」されるとありますが、 1.9 から出力されなくなっているようです。
```
% docker run -it --rm rubylang/all-ruby env ALL_RUBY_SINCE=ruby-1.6 ./all-ruby -e 'begin;raise "foo";rescue;abort;end'
ruby-1.6.0 -e:1: foo (RuntimeError)
exit 1
...
ruby-1.8.7-p374 -e:1: foo (RuntimeError)
exit 1
ruby-1.9.0-0 exit 1
...
ruby-2.7.0-preview3 exit 1
```
笹田さんに直接確認してみたところ、バグということだったので、チケットとして登録しておきます。
