[R] Display of NAs in character columns of a data frame under fix() or edit().

	xxx <- data.frame(x=1:26,y=letters)
	xxx$x[c(2,4,6,8)] <- NA
	xxx$y[c(1,3,5,7)] <- NA

	yyy <- edit(yyy)

The missing values in xxx$y appear as blanks in the spreadsheet window that
appears, whereas the missing values in the numeric column "x" appear as "NA"
(as I would expect).

Is this a bug or a feature?
