I see that I did update that answer, with

>At first glance, you might wonder what the point of opening a file that must have been empty in append mode is. Normally, of course, it might as well have been opened in standard out mode; the only difference would be if for some reason you had to use the modeless [`Reset`](http://www.ada-auth.org/standards/rm12_w_tc1/html/RM-A-10-1.html#p11). In that case, if the file was created in append mode it would remain in append mode, so any previous updates wouldn’t be lost.
