When stdin is a pipe, $stdin.tty? should return false. On JRuby-9.0.0.0-pre1 it returns true:

[matijs@walnut] rbenv shell jruby-9.0.0.0-pre1
[matijs@walnut] echo '' | ruby -e 'p $stdin.tty?'
true
[matijs@walnut] rbenv shell 2.2.0
[matijs@walnut] echo '' | ruby -e 'p $stdin.tty?'
false
[matijs@walnut] rbenv shell jruby-1.7.18
[matijs@walnut] echo '' | ruby -e 'p $stdin.tty?'
false

We probably have some special-case logic to always make stdio report it is a tty.
