Ugh. Take the first example in the paper; it rewrites as
len = asprintf(&path, "%s/.foorc");
as opposed to
strlcat(path, homedir, sizeof(path));
strlcat(path, "/", sizeof(path));
strlcat(path, ".foord", sizeof(path));
len = strlen(path);
Yes, they're a better str*cat/cpy, but they're not the solution that
they claim to be.
