R-alpha: ?bug in [.data.frame

If you subscript a data frame using the names of the columns and there is
more than one column with the same name only the first one is found.
	mm[,"(offset)"]			# only returns first column
	mm[,"(offset)"]<-rep(1,10)	# only sets first column

This *is* compatible with S, but I still think it's the wrong thing to do.
