Welcome aboard!

I was seeing test failures in t5302-pack-index.sh

Specifically tests 9 and 20
#   9: index v2: force some 64-bit offsets with pack-objects
#   20: create a stealth corruption in a delta base reference

These tests seem to be skipped these days if off_t isn't large enough,
I preferred the passing tests to the skipped ones. Maybe it isn't an
issue in the real world.
