-SRC_SIZE contains size of the source, when it was firstly read. BLK_SIZE
+SRC_SIZE contains size of the source, when it was initially read. BLK_SIZE
 is the blocksize used. Both are 64-bit big-endian unsigned integers. If
 either size or blocksize differs, then syncer will deny using that
 statefile as a precaution. HASHx is BLAKE2b-512 hash output, 64 bytes.
