commit aa212b173c340536eb94b4978174b068ead89cb1
Author: George Kadianakis <desnacked at riseup.net>
Date:   Thu Jun 14 18:01:22 2012 +0300

    Remove validate_pluggable_transports_config(): redundant since 9d9b5ed0.
    
    The warning message of validate_pluggable_transports_config() is
    superseded by the changes in the warning message of
    connection_or_connect() when the proxy credentials can't be found.
