When parsing the hideRefs configuration, we first duplicate the config value so that we can modify it. We then subsequently append it to the `hide_refs` string list, which is initialized with `strdup_strings` enabled. As a consequence we again reallocate the string, but never free the first duplicate and thus have a memory leak. While we never clean up the static `hide_refs` variable anyway, this is no excuse to make the leak worse by leaking every value twice. We are also about to change the way this variable will be handled so that we do indeed start to clean it up. So let's fix the memory leak by using the `string_list_append_nodup()` so that we pass ownership of the allocated string to `hide_refs`.
