#14068: Necessary line in tor-spec.txt

     Type:  defect     |         Status:  new
 Priority:  normal     |      Milestone:
Component:  Tor        |        Version:

-----------------------+---------------------
 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.
