What do you think about extending the tests
for ngx_http_link_multi_headers() ?
Searching for previous headers is a novel routine
so it might make sense to improve its coverage.

Something like this:

# HG changeset patch
# User Sergey Kandaurov <pluknet at nginx.com>
# Date 1654038532 -14400
#      Wed Jun 01 03:08:52 2022 +0400
# Node ID 3c2a768ef7e3eff6c943e0fa4dd10c9ec487c973
# Parent  83ec649296126965883e0d65c92ecd99f5397dc7
Tests: added fastcgi tests for catched bugs in combining headers.

This improves coverage in a search for previous headers.
