-When set, the fetch or receive will abort in the case of a malformed

-unreachable, see "QUARANTINE ENVIRONMENT" in

-instead be left unreferenced in the repository.

-Due to the non-quarantine nature of the `fetch.fsckObjects`
-implementation it can not be relied upon to leave the object store
-clean like `receive.fsckObjects` can.
-+
-As objects are unpacked they're written to the object store, so there
-can be cases where malicious objects get introduced even though the
-"fetch" failed, only to have a subsequent "fetch" succeed because only
-new incoming objects are checked, not those that have already been
-written to the object store. That difference in behavior should not be
-relied upon. In the future, such objects may be quarantined for
-"fetch" as well.

-For now, the paranoid need to find some way to emulate the quarantine
-environment if they'd like the same protection as "push". E.g. in the
-case of an internal mirror do the mirroring in two steps, one to fetch
-the untrusted objects, and then do a second "push" (which will use the
-quarantine) to another internal repo, and have internal clients
-consume this pushed-to repository, or embargo internal fetches and
-only allow them once a full "fsck" has run (and no new fetches have
-happened in the meantime).

-transfer.hideRefs::
-	String(s) `receive-pack` and `upload-pack` use to decide which
-	refs to omit from their initial advertisements.  Use more than
-	one definition to specify multiple prefix strings. A ref that is
-	under the hierarchies listed in the value of this variable is
-	excluded, and is hidden when responding to `git push` or `git
-	fetch`.  See `receive.hideRefs` and `uploadpack.hideRefs` for
-	program-specific versions of this config.
-+
-You may also include a `!` in front of the ref name to negate the entry,
-explicitly exposing it, even if an earlier entry marked it as hidden.
-If you have multiple hideRefs values, later entries override earlier ones
-(and entries in more-specific config files override less-specific ones).
-+
-If a namespace is in use, the namespace prefix is stripped from each
-reference before it is matched against `transfer.hiderefs` patterns.
-For example, if `refs/heads/master` is specified in `transfer.hideRefs` and
-the current namespace is `foo`, then `refs/namespaces/foo/refs/heads/master`
-is omitted from the advertisements but `refs/heads/master` and
-`refs/namespaces/bar/refs/heads/master` are still advertised as so-called
-"have" lines. In order to match refs before stripping, add a `^` in front of
-the ref name. If you combine `!` and `^`, `!` must be specified first.
-+
-Even if you hide refs, a client may still be able to steal the target
-objects via the techniques described in the "SECURITY" section of the
-linkgit:gitnamespaces[7] man page; it's best to keep private data in a
-separate repository.

-transfer.unpackLimit::
-	When `fetch.unpackLimit` or `receive.unpackLimit` are
-	not set, the value of this variable is used instead.
-	The default value is 100.
