2. Update to 20021129.

Changes since 20020628 (from FIXES file):
        modified b.c (with tiny changes in main and run) to support
        locales, using strcoll and iswhatever tests for posix character
        classes.  thanks to ruslan ermilov (ru@freebsd.org) for code.
        the function isblank doesn't seem to have propagated to any
        header file near me, so it's there explicitly.  not properly
        tested on non-ascii character sets by me.
