o Minor bugfixes: - Ensure that variables set in Tor's environment cannot override environment variables which Tor tries to pass to a managed pluggable-transport proxy. Previously, Tor would pass every variable in its environment to managed proxies along with the new ones, in such a way that on many operating systems, the inherited environment variables would override those which Tor tried to explicitly set. Bugfix on 0.2.3.12-alpha for most Unixoid systems; bugfix on 0.2.3.9-alpha for Windows.
