Comment (by dcf):

 Replying to [comment:8 asn]:
 > When Tor uses the wildcard transport in `TOR_SERVER_TRANSPORTS`, it also

 the

 This is the way I naturally interpreted the spec. You bind server ports
 that are
  1. listed in `TOR_PT_SERVER_BINDADDR`
  2. AND listed in `TOR_PT_SERVER_TRANSPORTS`
  3. AND are one of our supported transports.
 It's the intersection of three sets. When `TOR_PT_SERVER_TRANSPORTS=*`,
 you skip step 2 (i.e., intersect with the universe).
