R devel - Nov 2001 - rug(x) clip warning incorrect if par("xlog")==TRUE (PR#1188)

To wit:
> plot(1:2,1:2,log="x")
> rug(1:2)      # should not warn
Warning message: 
some values will be clipped in: rug(1:2) 
> plot(1:2,1:2,log="x")
> rug(c(0,.1,.2))  # should warn, but does not
> 
I believe this fixes the problem:
