libiberty: writeargv: Simplify function error mode.

You are right, this is also a remnant of the old function design
that I completely missed.    Here is the follow-up patch for that.

Thanks for pointing it out.

    Thanks.  I've pushed this to the trunk.

    You could (as a follow-up) simplify it even further.  There's no need
    for the status variable as far as I can tell.  You could just have the
    final return be "return 0;" instead of "return status;".
