If one wants to look up a value in a "value_string" table, and get back
either the corresponding string on success or NULL on failure, one
should use "match_strval()", rather than using "val_to_str()" with a
null format - "val_to_str()" uses the format if the lookup fails, so it
won't work correctly (e.g., it may drop core) if the format string is
NULL.
