I've decided to leave the Report as it is: no tabs, no newlines etc
in literal strings.  Use escapes and string gaps.  Rationale:
it's an unforced change; there's no consenus; and the general
feeling here is in any case to prohibit tabs, newlines in literal
strings.


Since its a no-op, I'm not posting this to the Haskell list.
