Thanks for working on this. Please add tests with files having multiple lines and we'll be golden!

@rauno56 Changed existing test to take multiple lines as input - I think we should be covered - thank you for the review - feel free to merge when you can.

Thanks for bearing with the long back-and-forth! I don't have any blockers.
Only curious about the length check.

[abhee11]

@rauno56 I strongly believe in code reviews like these ones, may be a bit long but it's a good learning and quality check. Thank you for an engaged review.
