Zephyrus draws them before a file's name only where the system gives no icon of its own (a Linux
desktop without an icon theme, a failed lookup), and for the moment before the system's icon is
ready (fileicons.rs). The computer and the network-workgroup icons stand for this computer and the
local network where a download's server is (whereis.rs), in the place of a country's flag.
