ERROR 2002 printed a socket path MySQL never dialed: the message stops at 100 characters

Automated excerpt

I passed --socket a path ending in . sock, and the error came back with the last three characters gone. The path in that message is not the path the client dialed, and on MySQL 26. 7. 0 it never can be once the path gets long enough — the message stops at 100 characters. One socket path, 103 characters, which is legal.
