Fixed now for r-devel. Will commit shortly.

(Martin, here's a way to test all characters:

 x <- y <- unlist(as.list(
   parse(text=paste("\"\\",
         as.character(structure(0:255,class="octmode")),
         "\"",sep=""))))
 save(x, ascii=T, file="here")
 load("here")
 all(x==y)

- I'd commit it for the regression test suite, but I'm not sure what
our conventions are for temporary files)

BTW: printing and deparsing x and y causes display corruption. Perhaps
we should have an isprint somewhere?
