Unecessary line in tor-spec.txt
Section 4.1 of tor-spec.txt contains the following line:
When the "in-protocol" handshake is used, implementations MUST NOT list any version before 3, and SHOULD list at least version 3.
tTe spec states that implementations SHOULD use at least version three, indicating that they may choose to do othereise. However, this is made redundant by the previous clause of the sentence, which states that any version below three MUST NOT be used.
Using SHOULD implies that another option is available, when in reality no other choice is possible, without breaking the MUST NOT clause.
