It is this one, where the "+" means concatenation.  Most implementations
of hash functions do not require you to literally concatenate the data,
but rather you can pass the data in pieces, so you first pass in a, then
b, then c.  In the spec we write this as "first hash a, then hash b, then
hash c," and so on.
