In addition to Observable, $ or _, we should also add `this` to the list of things that are likely factory and not objects you want to apply things on directly.
I added a way to make the function call break on its own line when it doesn't fit in one line and indent. But I think that only having the indentation is enough, having the call on its own line feels weird.
Fixes#777
Before, we would always concatenate the first `.call()` if the identifier started with a capital letter, but we do want to break if the content of the call doesn't fit in one line.
Fixes#639
