[PATCH v2 0/4] bundle: show progress on "unbundle"

This straightforward series addr progress output on "git bundle unbundle", we already had progress output if bundles were fetched from via the transport.c (i.e. "git clone/fetch" etc.), but not from "git bundle unbundle" directly.

This was submitted as https://lore.kernel.org/git/cover-0.4-0000000000-20210727T004015Z-avarab@gmail.com/ before v2.33, hopefully now with the release out these rather trivial patches can be queued up. The only change since v1 is an extended commit message in 3/4 discussing the initial motivation for this change.

Ævar Arnfjörð Bjarmason (4):
  bundle API: start writing API documentation
  bundle API: change "flags" to be "extra_index_pack_args"
  index-pack: add --progress-title option
  bundle: show progress on "unbundle"
