     11  * Before lex.c 1.47 from 2021-06-29, lint intended to detect a "bad octal
     12  * digit" following good octal digits, but the corresponding code had an
     13  * unsatisfiable guard clause.
     14  *
     15  * The C Reference Manual 1978, 2.4.3 "Character constants" does not mention
     16  * non-octal digits, therefore this code must have been due to a particular
     17  * C compiler's interpretation.  It's even wrong according to the Reference
     18  * Manual to interpret '\088' as anything else than a malformed character
     19  * literal.
     20  *
     21  * That code has been removed since nobody runs lint in traditional C mode
     22  * anyway.
