Fix bug in initialization of auto arrays of strings.

When initializing (e.g.) an array of arrays of char, a string literal would be taken as an initializer for the outer array rather than for an inner array, so not all elements would be initialized properly. This was a bug introduced in commit 222c34a385.

This bug affected the C4.6.4.2.CC test case, and the following reduced version:

#include <stdio.h>
#include <string.h>
int main (void) {
   char ch2[][20] = {"for all good people", "to come to the aid "};
   if (strcmp(ch2[1], "to come to the aid "))
       puts("Failed");
}
