[tor-commits] [tor/master] Clients no longer write "DirReqStatistics 0" in their saveconf output

commit 905443f074088cbc6322341e5c1cd6b35cd363a8
Author: Roger Dingledine <arma@xxxxxxxxxxxxxx>
Date:   Wed Sep 10 23:01:18 2014 -0400

    Clients no longer write "DirReqStatistics 0" in their saveconf output
    
    Stop modifying the value of our DirReqStatistics torrc option just
    because we're not a bridge or relay. This bug was causing Tor
    Browser users to write "DirReqStatistics 0" in their torrc files
    as if they had chosen to change the config.
    
    Fixes bug 4244; bugfix on 0.2.3.1-alpha.
