commit e5792992e5d6e73bb379bbfcd69ae2e66afe359d
from: Omar Polo <op@omarpolo.com>
date: Fri Oct 28 11:28:02 2022 UTC

change add_delta to take an off_t instead of size_t.

add_delta already calls got_delta_open casting the size_t to off_t, and
all the add_delta callers pass an off_t anyway; fixes an implicit off_t
truncation.
