Comment (by yawning):

 {{{
 If the client PT finds out that the TOR_PT_PROXY environment
 variable is set, the PT is expected to use that as an outgoing
 proxy.
 }}}

 I would prefer something like:
 {{{
 If the client PT is provided with a TOR_PT_PROXY environment
 variable, it MUST make all outgoing network connections via the
 supplied proxy.  If it is unable to do so for any reason (eg:
 malformed value, unsupported proxy type, unreachable proxy
 address), it MUST return a `PROXY_ERROR` and terminate.
 }}}

 Adjust language to taste.  The hard-failure requirement should explicitly
 be listed in the pt-spec instead of being buried in a proposal (as a
 MUST).
