    delta-apply: fix sign extension We compute offsets by executing `off |= (*delta++ << 24)` for multiple constants, where `off` is of type `size_t` and `delta` is of type `unsigned char`. The usual arithmetic conversions (see ISO C89 ยง3.2.1.5 "Usual arithmetic conversions") kick in here, causing us to promote both operands to `int` and then extending the result to an `unsigned long` when OR'ing it with `off`. The integer promotion to `int` may result in wrong size calculations for big values. Fix the issue by making the constants `unsigned long`, causing both operands to be promoted to `unsigned long`.
