As an extra optimization, when `prepare_bitmap_walk` succeeds, the
`reuse_partial_packfile_from_bitmap` call can be attempted: it will find
the amount of objects at the beginning of the on-disk packfile that can
be reused

Yay! This is similar to the optimization we use in JGit to send the

In fact, I'm not quite sure that even a partial reuse up to an offset is

before deltas (and OFS_DELTA objects need this). But if you had a bitmap

Yes, our pack writing and bitmap code takes enough precautions to
arrange the objects in the packfile in a way that can be partially
reused, so for any given bitmap file written from Git, I'd say we're
safe to always reuse the

If `prepare_bitmap_walk` runs successfully, the resulting bitmap is
