So I found that I can make the code more reasonable with this simple
coding,

    if (maxlen > 0)
    {
        s = pnstrdup(s, maxlen);
        ellipsis = strnlen(s, maxlen + 1) > maxlen;
        /* enlarge while we can do so cheaply */
        enlargeStringInfo(str, maxlen);
    }

... but the problem is that we now compile stringinfo.c for frontend
environments also, and there's no pnstrdup() in frontends.  And to
introduce it, we'd need a configure check (because GNU libc has it) and
a src/port naive implementation and a fe_memutils.c addition.

Sigh.

Still, it's not that much code, so I'll just go do that and open a
separate thread for it.
