Section Public Key Cryptography has a table of prefixes and Examples below.

There are discrepancies between them:
0xEB5AE987 in table for Secp256k1 pubkey, but EB5AE982 in example
0x7FC4A495 in table for Secp256k1 signature, but 16E1FEEA bytes in example

I see the table was changed during one commit (d47b4ef), but examples section haven't.
