When wget is called with -r or -p it will look for resource tags in the
output file, and since -O- redirects to stdout, the program hangs, waiting
for input. The same happens with pipes or FIFO files.
My proposed solution is to disallow calling wget with '-p' or '-r' and
output redirection to either stdout or a FIFO file.
