Include stripped newlines

[arturcarvalho]

If I understand correctly, the \n is being stripped:

tail/tail.go

Line 244 in 4472660

line = strings.TrimRight(line, "\n")

Is this trim necessary? It's causing me issues, because later I can't distinguish between line endings and regular \r (I'm joining all the text).

I suppose I can add some logic to add the \n again, but it seems a bit redundant.

Thanks and thank you very much for the library!

I've commented the line out and it works for my use case. Do you think it would make sense to add a configuration flag to turn on/off the trim? I'd be happy to provide a PR.
