Hurray.

This may be momentarily puzzling, if you don't realize that "their
elements" includes the trailing null character.  So, given:

    char *p = "classes", *q = "lasses", *r = "asses", *s = "ass", *t = "as";

it will now be permissible for any or all of p+2, q+1, and r to point to
the same byte of storage, but s and t must still each be different.
The change resolves an ambiguity as to the meaning of "identical string
literals" in the existing standard; remember that "c" "l" "asses" is
effectively equivalent to "classes".
