Force param deprecated in puppetlabs/concat v2

[liquorvicar]

I've started to get warnings about this in some of my manifests. I've fixed it for now by fixing on v1.2.3 of puppetlabs/concat but do you have plans to fix this? Obviously it's a small actual change (just remove that param from the concat_emitter.pp file but I'm not sure whether it might have implications?

@mburger any input on this?
