When dropping 1.8.7 support, I blindly removed this check, because the comment above it suggested that it was 1.8.7-specific.

However, the check is also needed for rb-readline, the default readline implementation on modern rubies under Windows. See https://github.com/ConnorAtherton/rb-readline/blob/9fba246073f78831b7c7129c76cc07d8476a8892/lib/readline.rb#L91-L97.

So, I'm restoring the check, and the specs changes that I included in the 1.8.7 support drop commit to get specs passing.

`rb-readline`, the default readline implementation that currently comes
with Windows, does not allow `nil` to be passed in here because it
doesn't respond to `call`. See: https://github.com/ConnorAtherton/rb-readline/blob/9fba246073f78831b7c7129c76cc07d8476a8892/lib/readline.rb#L91-L97
