Log message:
        * src/builtin.c (numeric_arg): Treat empty string as 0, with a
        warning.  Detect quoted leading space and overflow as warnings.
        (m4_eval): Treat empty radix as 10, and allow output in radix 1.
        Treat width as minimum number of digits, as required by POSIX.
        (m4_ifdef, m4_divert, m4_m4exit, m4_translit): Ignore extra
        arguments.
        (m4_substr): Likewise.  Silently treat empty start as 0.
        (m4_undivert): Treat ` 1a' as file, not diversion 1.
        * src/eval.c (eval_lex): Parse radix 1 numbers.
        * doc/m4.texinfo (Invoking m4): Fix wording; there is more than
        one type of warning.
        (Manual): Document behavior of numeric parsing of empty string.
        (Divert, Incr): Document error handling.
        (Eval): Document radices better.
        (Incompatibilities): Document translit incompatibility.
        * NEWS: Document these changes.
