So, the version I queued looks like so:

        diff --git a/help.c b/help.c
        index ce55aaa2c0..92bfef140b 100644

but then there are a few "side builds" at GitHub CI, one of which is
"minimum fuzzer" build.  It compiles bunch of object files without
giving much build options but the final target of the build is not
"git" but something else [*].  And because the job is not interesting
in building a working "git", the environment does not install libcURL,
leading to a failed build.

I sent a separate patch to address this build failure, which is
found at https://lore.kernel.org/git/xmqqwmmhimxx.fsf@gitster.g/
