Re: [PATCH v3] repository: move fetch_if_missing into struct repository

> The global variable 'fetch_if_missing' controls whether a missing
> object check should prompt a lazy fetch from a promisor remote.
> In order to continue the libification effort, move it into
> 'struct repository' and initialize it to 1 by default to keep the
> previous behavior.
>
> Note that in builtin/fsck.c and builtin/index-pack.c, when running
> related commands with the '-h' parameter, the 'repo' pointer is not
> passed in. To prevent null pointer dereferences, we defer
> operations on the repo until after parameter parsing is complete.
>
> Additionally, update the partial clone documentation to reflect
> that this is now a per-repository flag.
