mblen.3 asserts mblen(3) is from ISO C89

[Steffen "Daode" Nurpmeso <sdaoden%gmail.com@localhost>]

Shouldn't this be ISO C90 (even Addendum 1? ..but haven't found
a mandoc symbol for that)?
I can't find an english version of pre-C99, but can assure you
that my german translation of ANSI C, i.e., "The C Programming
Language, Second Edition, ANSI C", does not mention it.
