[PATCH 0/4] midx repack: fix overflow on 32 bit systems

[Phillip Wood <phillip.wood123@gmail.com>]

From: Phillip Wood <phillip.wood@dunelm.org.uk>

This series fixes an overflow when running "git multi-pack-index
repack" on an old raspberry pi and a couple of other small issues I
noticed while reading the code. I'm unsure how realistic the example
of integer overflow on 64 bit systems in patch 2 is. I'm happy to drop
it if people who work with large repositories think its not worth
worrying about.
