I've downloaded the source package and debugged it... this seems related to a bug that is being discussed on the wget mailing list at the following url: http://lists.gnu.org/archive/html/bug-wget/2016-02/msg00033.html
They say this happens with a small terminal window... but on me it happens no matter how big the terminal is... i've tried to run wget with "quiet" mode and also chanding the progress from "bar" to "dot" and it works ... anyways this is the backtrace done with gdb and you can see the padding is negative. Hope it helps :-) evan@HPPC:~/Scaricati/wget-1.17.1/src$ gdb --args ./wget http://releases.ubuntu.com/16.04/ubuntu-16.04-desktop-amd64.iso GNU gdb (Ubuntu 7.11-0ubuntu1) 7.11 Copyright (C) 2016 Free Software Foundation, Inc.
