Automatically killing the download buffer is a little trickier. The
download-info object doesn't have a references to buffers displaying its
information. (You can have more than one download buffer monitoring a
single download.)
So, thinking this through, you would need a hook that runs any time a
download-buffer is created, which plants a kill callback in the buffer's
download-info. Something like this:
function install_download_buffer_closer (b) {
if (b instanceof download_buffer) {
add_hook.call(b.info, "download_finished_hook",
function () {
kill_buffer(b);
});
}
}
add_hook('create_buffer_hook', install_download_buffer_closer);
