[tor-commits] [tor/master] Use %f, not %lf when formatting doubles

    Use %f, not %lf when formatting doubles
    
    %f is correct; %lf is only needed with scanf.  Apparently, on some
    old BSDs, %lf is deprecated.
    
    Didn't we do this before?  Yes, we did.  But we only got the
    instances of %lf, not more complicated things like %.5lf .  This
    patch tries to get everything.
    
    Based on a patch for 3894 by grarpamp.
