    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;".

            * argv.c (writeargv): Constant propagate "0" for "status",
            simplifying the code slightly.
