* src/include/lib.h (array_size): Rename to... (array_length): ...this. * src/preproc/eqn/box.cpp (set_param, reset_param, get_param) (init_param_table, free_param_table): Migrate call sites. Thanks to Alex Colomar for the discussion. See <https://lists.gnu.org/archive/html/groff/2023-08/msg00140.html>. Acked-by: Alejandro Colomar <alx@kernel.org>
