The function raw_string() assigns the class xfun_raw_string to
the character vector, and the corresponding printing function
print.xfun_raw_string() uses cat(x, sep = '\n') to write the
character vector to the console, which will suppress the leading indices
(such as [1]) and double quotes, and it may be easier to read the
characters in the raw form (especially when there are escape sequences).
