I'd expect to encounter a lot of problems with (char **) arrays where
every element of the array is (or not) metafied.  (Hopefully there
aren't any that are mixed).  As was noted in the discussion of passing
around lengths of arrays when manipulating array parameters, the older
code makes a lot of assumptions about pointer arithmetic and s[1][1]
subscripting and so on.
