Yes, lynx should do something like this.  At least for HTTP files, if
they come with a Content-length header.  Lynx should compare the total
of bytes received with the expected length.

This won't work with the current implementation of byte counting for
the statusline progess message.  The statusline counter implementation
starts counting at the wrong point in the data stream: after the first
buffer, normally 1 network packet, has been read and processed.  It
should start counting exactly where the message body starts (which may
be later or earlier or coincide, depending on factors out of lynx's
control).  That probably means the counter should be (re-?)set to 0
somewhere in HTMIME.c, since that's where the end of HTTP headers is
detected.
