Support multiline input with user `eval` function

[blakeembrey]

Currently, the node repl module has the capability to do multiline input when the error is an instanceof Recoverable. Unfortunately, the constructor is not exported from the repl module which results in hacky ways to achieve a multi-line REPL experience like node. By exporting the error constructor, consumers could create their own recoverable instances to function identical to before and have multi-line input work naturally.

Edit: Mostly a question, if it's reasonable to add I can issue a PR for a one-line export change.

@blakeembrey Exporting recoverable might be a simpler solution to what I was proposing in my pull request and I think simple is good. I guess we need some input as to which would be preferred. I think it would be good to submit your pull request 👍
