Global variable `$INPUT_RECORD_SEPARATOR' not initialized on ruby 2.0.0-p0

[webervin]

Using ruby 2.0.0-p0 via rbenv.

When i have '$/' in file i get cop 'Prefer $INPUT_RECORD_SEPARATOR over $/.'
However if replace $/ with $INPUT_RECORD_SEPARATOR
I get warning
W: 15: Global variable `$input_record_separator' not initialized
(wich is true as such variable seems not to exist, returning nil when queried in irb)

Offending file example

Some of the proper global variables are not defined unless you do require 'english'. This is one of them. I guess the message could be more informative.

[bbatsov]

The English library is now mentioned where relevant. For instance the message you got will now be 'Prefer $INPUT_RECORD_SEPARATOR from the English library over $/.'

This should also be removed from the autocorrect. It just failed my tests in a way that wasn't very obvious at first.
