From b664e9ffa153189dae9b88f32d1c5fedcf85056a Mon Sep 17 00:00:00 2001 From: Jonathan Tan Date: Mon, 22 Feb 2021 11:20:08 -0800 Subject: [PATCH] fetch-pack: with packfile URIs, use index-pack arg Unify the index-pack arguments used when processing the inline pack and when downloading packfiles referenced by URIs. This is done by teaching get_pack() to also store the index-pack arguments whenever at least one packfile URI is given, and then when processing the packfile URI(s), using the stored arguments.
