eliminate invalid "ptr += (ptr2 - ptr1)"
* lib/savedir.c (savedir): new_name_space and name_space do not point into
the same object, so computing their difference is invalid. Similarly,
summing the difference to namep is invalid because namep and the result
point into different objects. Avoid this.
