As near as I can make out, 'who' is violating the POSIX specification
when it truncates the user name.  Also, I notice that Solaris 8 'who'
does not truncate.  I don't see any good reason for 'who' to truncate,
so here's a patch.

2004-06-19  Paul Eggert  <address@hidden>

        * src/who.c (print_line): Don't truncate user names at 8 bytes.
        Problem reported by Guido Leenders in:
        http://lists.gnu.org/archive/html/bug-coreutils/2004-06/msg00056.html
        * NEWS: document this.
