Eric Blake 2f49d755e5 Stage 19b: invert sense of bit for handling builtin tokens.
* m4/m4module.h (M4BUILTIN_ENTRY): New convenience macro.
(M4_BUILTIN_GROKS_MACRO): Rename...
(M4_BUILTIN_FLATTEN_ARGS): ...and invert sense.
(m4_symbol_value_groks_macro, m4_symbol_groks_macro): Likewise...
(m4_symbol_value_flatten_args, m4_symbol_flatten_args): ...to
this.
* m4/m4private.h (VALUE_MACRO_ARGS_BIT)
(m4_symbol_value_groks_macro): Likewise...
(VALUE_FLATTEN_ARGS_BIT, m4_symbol_value_flatten_args): ...to
this.
* m4/symtab.c (m4_symbol_value_groks_macro): Likewise...
(m4_symbol_value_flatten_args): ...to this.
* m4/macro.c (collect_arguments): Accomodate changed sense.
* m4/module.c (m4__module_open): Require arguments if flattening
is requested.
* m4/input.c (m4_push_string_finish): For now, flatten all
builtins pushed as back-references.
* modules/gnu.c (m4_builtin_table, builtin): Adjust all clients.
* modules/import.c (m4_builtin_table): Likewise.
* modules/load.c (m4_builtin_table): Likewise.
* modules/modtest.c (m4_builtin_table): Likewise.
* modules/mpeval.c (m4_builtin_table): Likewise.
* modules/perl.c (m4_builtin_table): Likewise.
* modules/shadow.c (m4_builtin_table): Likewise.
* modules/stdlib.c (m4_builtin_table): Likewise.
* modules/time.c (m4_builtin_table): Likewise.
* modules/m4.c (m4_builtin_table): Likewise.
(mkstemp): Undo #undef hack from 2006-10-23, now that macro names
are stringized without preprocessor expansion.
* doc/m4.texinfo (Defn): Update comments to match reality.
(Debuglen): Update test now that user macros pass builtin tokens.
