In version 1.0.0, Header List ends when the first relay bandwidth
is found conforming to the next section. Implementations of version 1.1.0 and later SHOULD use a 5-character
terminator. Tor 0.4.0.1-alpha and later look for a 5-character terminator,
or the first relay bandwidth line. sbws versions 0.1.0 to 1.0.2
used a 4-character terminator, this bug was fixed in 1.0.3.
