Is this something that might belong in the humanize filters package?
Either something like {{ quantity|currency }}, which takes the
currency type from locale, if in use, or else explicitly with
{{ quantity|currency:"USD" }}? It's not a great savings over just
doing it from scratch, but that's the sort of thing that seems to
belong in humanize...
