/*
 * Lookup a resource bundle table item with fallback on the table level.
 * Regular resource bundle lookups perform fallback to parent locale bundles
 * and eventually the root bundle, but only for top-level items.
 * This function takes the name of a top-level table and of an item in that table
 * and performs a lookup of both, falling back until a bundle contains a table
 * with this item.
 *
 * Note: Only the opening of entire bundles falls back through the default locale
 * before root. Once a bundle is open, item lookups do not go through the
 * default locale because that would result in a mix of languages that is
 * unpredictable to the programmer and most likely useless.
