Hi, thanks for the PR!

Looks good, one small thing - could you add some test cases to prevent us running into some regression in the future? The output is tested here https://github.com/softwaremill/diffx/blob/master/core/src/test/scala/com/softwaremill/diffx/test/DiffResultTest.scala

Yes, I will expand the PR with some test.

I realise that the root issue was that I was comparing lists of Protobuf objects, that have a custom toString method that produced multiline output (I cannot control it, it is a Protobuf decision).
