[Patterns] Document on exhaustiveness, unconditionality and remainder

[Jens Lideström]

This is a very informative document!

I don't find any mention of when the null value is accepted by type patterns. I would expect that to be discussed in the section "Nested patterns". Since this depends on whether a pattern is unconditional maybe the document should say something about it?
