+FTP PORT command code in v1.16.3?
+
+In the past it could be possible for a site over http connection to
+redirect wget to FPT using FTP PORT command so the site gets the real IP
+of the computer even when wget proxy command is in use I believe:
+https://lists.torproject.org/pipermail/tor-talk/2012-April/024040.html
+
+Is that code still present in wget v1.16.3? It was present in v1.13.4.
