Well, I believe that validate_config_strvec() would have made sure
that VECTOR_SLOT(strvec, 1) exists and is non-NULL before set_int() is
called via keyword->handler(). Also, if we want to make this more
robust, we might want to use strtol() rather than atoi() to check for
an actual int argument.
Anyway:
