Stage 20b: make m4wrap obey POSIX fifo ordering.
* m4/m4module.h (m4_wrap_args): Add prototype.
* m4/m4private.h (enum m4__symbol_chain_type): Add M4__CHAIN_LOC.
(struct m4__symbol_chain): Add struct u_l.
* m4/input.c (m4_push_wrapup_init, m4_push_wrapup_finish): Use
new link type.
(composite_peek, composite_read, composite_clean): Handle location
link.
* m4/macro.c (m4_wrap_args): New function.
* modules/m4.c (m4wrap): Use it.
* doc/m4.texinfo (M4wrap): Sync with branch and POSIX.
(Extensions): Document extension of multiple arguments.
(Location, Improved m4wrap): Adjust example to match FIFO order.
* tests/builtins.at (wrap): Likewise.
* NEWS: Document this change.
