Macro gettextrs::dngettext

macro_rules! dngettext {
    ($domainname:expr, $msgid:expr, $msgid_plural:expr, $n:expr, $($args:expr),+ $(,)?) => { ... };
}

Like dngettext, but allows for formatting.

It calls dngettext on domainname, msgid, msgid_plural, and n, and then replaces each occurrence of {} with the next value out of args.
