-/* using allocating hyphenation trie slows things down maybe 1% */
-/* but saves typically (270k - 55k) = 215k of memory */
-/* NOTE: it's safe to allocate based on the trie_max read from fmt file */
-/* since hyphenation trie cannot be extended (after iniTeX) */
-/* for iniTeX, however, we need to allocate the full trie_size ahead of time */
