Log message:
        Rename --warn-syntax to --warn-macro-sequence[=regex], to make it
        more flexible, and so that autoconf can use it.
        * src/m4.h (set_macro_sequence, free_macro_sequence): New
        prototypes.
        * src/builtin.c (macro_sequence_buf, macro_sequence_regs)
        (macro_sequence_inuse, set_macro_sequence, free_macro_sequence):
        New variables and functions.
        (define_user_macro): Allow flexibility in regular expression used
        to trigger warning.
        * src/m4.c (warn_syntax): Delete.
        (usage, WARN_MACRO_SEQUENCE_OPTION, main): Implement changed
        spelling of option, along with optional argument.
        * doc/m4.texinfo (Operation modes, Arguments): Document this
        change.
        * NEWS: Document this change.
