- update to 20230521:
  * error.c, defs.h, reader.c:
    allow @1 or $@ with a warning if no %locations was given
  * reader.c: clear pointer in end_ainfo() after freeing it.
  * reader.c: report errors in %define as "unexpected value"
    add/use macros begin_ainfo() and end_ainfo() to reduce clutter
  * defs.h, error.c: add function unexpected_value()
  * add %nterm as an alias for %type, since bison made that confusion.
  * reader.c:
    ensure that filler_buf and prefix_buf are initialized for the special case
    where they are empty (report by Martin Jansa, cf: 20230219)
  * output.c:
    make test-differences smaller when compiling with YY_NO_LEAKS by replacing
    a blank line with the generated #define rather than adding 3 lines.
  * reader.c:
    correct a use-after-free in more_curly, which could occur if a %lex-param
    or %parse-param was multi-line (Redhat #2183006).
  * main.c: rename no_space() to on_error()
  * error.c: rename no_space() to no_error(), handling any errno
  * defs.h: rename no_space() to on_error()
