 If I start the latest tor code with `--ControlPort=auto` and
 `--ControlPortWriteToFile=/path/to/file`, then the contents of the file
 end up as `PORT=127.0.0.1:0`, which is kind of useless :)

 I guess some code got messed up lately that updates the port before
 writing it out to the control file.
