A comment in city.h says:
// By the way, for some hash functions, given strings a and b, the hash
// of a+b is easily derived from the hashes of a and b. This property
// doesn't hold for any hash functions in this file.
But I didn't find how it can be done. It would be nice to have this feature.
For example, it can be used to hash a data stream that becomes available one
block at a time, but the block sizes are arbitrary, and we need both the hash
of each block and the hash of the whole stream (invariant of block sizes).
