I should have been clearer in my original question: I'm curious about what to do when a multi-argument function application gets split across lines. That wiki page dicsusses how the layout rule interacts with various special forms (let, where, if, do, case), but it doesn't seem to address function applications, beyond implying that it's ok to indent the continuing lines of a function application.
It looked pretty explicit to me: The golden rule of indentation ... you will do fairly well if you just remember a single rule: Code which is part of some expression should be indented further in than the beginning of that expression (even if the expression is not the leftmost element of the line). This means for example that f (g x y z) is OK but f (g x y z) is not.
