(and, of course, the escape character). Canonical unparsing: NIL, !H, !L, !*, !num as appropriate. Parsing names in Cedar filename form. parses a component beginning at name[first] and returns that component; next = first + length of the parsed component. bug: should interpret escape sequences. parses a version beginning at name[first] and returns that version; next = first + length of the parsed version. A convenient way to read a whitespace-delimited name from a stream.
