[PATCH 0/5] builtin/repack: make geometric repacking compatible with promisors

Hi,

I recently noticed that geometric repacking is incompatible with promisor remotes. This is because we invoke git-pack-objects(1) with both "--stdin-packs" and "--exclude-promisor-objects", and those flags are mutually exclusive. Next to us dying though, we also don't have any logic to mark merged packs as promisors in case any of the source packs was a promisor.

This patch series fixes this by making these flags work with one another and by introducing special handling for promisor packs during geometric repacks.

Thanks!

Patrick
