Is this correct?
You still keep cached_accept_language pointer itself, so the next
call to get_accept_language() would say "Ah, cached_accept_language
is there, so its contents (which is empty because we released it
here) must be valid and to be reused". Perhaps you want to free it,
too, i.e.
if (cached_accept_language) {
strbuf_release(cached_accept_language);
free(cached_accept_language);
cached_accept_language = NULL;
}
or something?

Have that "empty statement" on its own separate line, i.e.
for (a, counter = 0;
b;
c, counter++)
; /* just counting */
Alternatively, you can make it more obvious that the purpose of loop
is to count, i.e.
for (a, counter = 0;
b;
c)
counter++;

Hmph, this test smells a bit brittle. What is the reason you expect
"git clone" to fail? Is it because there is no repository at the
named URL at "$HTTPD_URL/accept/language"? Is that the only plausible
reason for a failure?
It might be better to use the URL to a repository that is expected
to be served by the server started in this test and expect success.
If it bothers you that "clone" creates a new copy that is otherwise
unused by this test, you can use something like "ls-remote" instead,
I would think.
