OR patterns in `let` chains are formatted without indentation

        let hir = tcx.hir();
        if let Some(body_id) = tcx.hir_node_by_def_id(def_id).body_id() {
            tcx.arena.alloc_from_iter(hir.body_param_names(body_id))
        } else if let Node::TraitItem(&TraitItem {
            kind: TraitItemKind::Fn(_, TraitFn::Required(idents)),
            ..
        })
        | Node::ForeignItem(&ForeignItem {
            kind: ForeignItemKind::Fn(_, idents, _),
            ..
        }) = tcx.hir_node(tcx.local_def_id_to_hir_id(def_id))
        {
            idents
        } else {
            span_bug!(
                hir.span(tcx.local_def_id_to_hir_id(def_id)),
                "fn_arg_names: unexpected item {:?}",
                def_id
            );
        }

The indentation on this else if let is very confusing as it looks like the if else ends because we are at "normal" indentation for statements in the body, which makes it look like someone has written an assignment with a pattern with a leading | which is then somehow followed up by a block with an else on the end of it (?)

Something like the following would be significantly clearer as the indentation signifies that this is inside of the else condition:

        let hir = tcx.hir();
        if let Some(body_id) = tcx.hir_node_by_def_id(def_id).body_id() {
            tcx.arena.alloc_from_iter(hir.body_param_names(body_id))
        } else if let Node::TraitItem(&TraitItem {
                kind: TraitItemKind::Fn(_, TraitFn::Required(idents)),
                ..
            })
            | Node::ForeignItem(&ForeignItem {
                kind: ForeignItemKind::Fn(_, idents, _),
                ..
            }) = tcx.hir_node(tcx.local_def_id_to_hir_id(def_id))
        {
            idents
        } else {
            span_bug!(
                hir.span(tcx.local_def_id_to_hir_id(def_id)),
                "fn_arg_names: unexpected item {:?}",
                def_id
            );
        }

Relatedly consider the following two code examples:

else if let Node::TraitItem(&TraitItem {
    kind: TraitItemKind::Fn(..),
}) | Node::ForeignItem(&ForeignItem {
    kind: ForeignItemKind::Fn(..),
}) = tcx.hir_node()
{
    x
}

and

else if Node::trait_item() {
    TraitItemKind::Fn(..),
} else if let Node::ForeignItem(&ForeignItem {
    kind: ForeignItemKind::Fn(..),
}) = tcx.hir_node()
{
    x
}

The former has incredibly similar structure to the latter despite having incredibly different meaning and the only distinction is | let which is very easy to miss when skimming the code.
