From 2c5e2865cc3dfc053e71510415f479e165119d04 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Fri, 24 Mar 2017 13:26:50 -0400 Subject: pack.h: define largest possible encoded object size Several callers use fixed buffers for storing the pack object header, and they've picked 10 as a magic number. This is reasonable, since it handles objects up to 2^67. But let's give them a constant so it's clear that the number isn't pulled out of thin air.
