Comment (by dcf):

 pyptlib allows "*" to appear as an element in a list of other transports.
 It sets the `allTransportsEnabled` which is read later.
  * https://gitweb.torproject.org/pluggable-
 transports/pyptlib.git/blob/0030aa880a94199627abe0891607416333b2e0eb:/pyptlib/config.py#l39
  * https://gitweb.torproject.org/pluggable-
 transports/pyptlib.git/blob/0030aa880a94199627abe0891607416333b2e0eb:/pyptlib/core.py#l81

 goptlib uses the interpretation that only the exact string "*" has a
 special meaning. It causes the library to immediately return user's entire
 transport list.
  * https://gitweb.torproject.org/pluggable-
 transports/goptlib.git/blob/78e518c824d9541056ba2ca870df2bb01b810b05:/pt.go#l200

 transports/goptlib.git/blob/78e518c824d9541056ba2ca870df2bb01b810b05:/pt.go#l333

 Another interesting use case for "*": flashproxy-client wants to support
 the two transport names "flashproxy" and "websocket" as aliases. You can
 ask for either one in `TOR_PT_CLIENT_TRANSPORTS` and flashproxy-client
 will open up a listener for you. But when we get "*", we only want to use
 one of them (flashproxy), not both.
