walker: let walker_say take arbitrary formats
We take a printf-style format and a single "char *" parameter, and the format must therefore have at most one "%s" in it. Besides being error-prone (and tickling -Wformat-nonliteral), this is unnecessarily restrictive. We can just provide the usual varargs interface.
