Comment (by cyberpunks):

 Replying to [comment:2 teor]:
 > No, duplicate subprotocol entries are allowed by the spec:

 That spec seems ambiguous and could be clarified in either direction.

 If it's clarified to forbid duplicates--it already says the entries should
 be sorted alphabetically--it would become simpler to also verify that
 there aren't any overlapping ranges, which the spec says shouldn't happen
 but the C implementation doesn't check for right now.

 Also, `make test-network-all` passes on branch protodupes1, at least.
