It's possible to write the dup of struct reg_substr_datum with a
memcpy() replacing the member by member copy. Curiously gcc's -Os
produces the same sized code, but not all optimisers may manage this.
Also, by reading and re-assigning to the copied data for the sv_dup()s
we hope to avoid any cache misses on the copied from data.
