-From 87e178e98713539ac5e543c34520cc7aca3d8c03 Mon Sep 17 00:00:00 2001
-From: Lars Francke <git@lars-francke.de>
-Date: Mon, 20 Oct 2025 08:36:40 +0200
-Subject: Fix problem where multi-chars delimiters fail to be parsed if they
- happen right at a buffer boundary.
-
-This can be removed when we use the version of Vector that includes this
-fix.
-See: https://github.com/vectordotdev/vector/pull/24028
-
-NOTE: async/await removed from the patch, because async is added after
-0.49.0.
