z4cx should be changed to z04cx here:

       In the remaining forms, a field is created for each number starting at
       n1. This continues until it reaches n2 and increments n1 by n3. The
       cases where n3 is not specified behave as if n3 were 1 if n1<=n2, and
       -1 otherwise. In forms which specify %fmt, any format flags, widths and
       precisions can be specified and fmt can end in any of the specifiers
       cdiouxX. For example, {a,z}{1..5..3%02d}{b..c}x expands to the 8
       fields, a01bx, a01cx, a04bx, a04cx, z01bx, z01cx, z04bx, and z4cx.
