Comment:

 I turned Roger's patch into a pull request on GitHub:
 https://github.com/torproject/tor/pull/1622

 The patch worked for me. When using a 192.168.0.0/16 address in
 `ServerTransportListenAddr`, tor rewrote it to my machine's external IP
 address. I tested it by taking a look at my bridge's extrainfo descriptor
 on BridgeDB.

 My branch is based on master and I created a changes file as the documents
 in doc/HACKING/ told me. Let me know if there's anything wrong with the
 patch and I'll be happy to fix it.
