Macro gettextrs::dcgettext

macro_rules! dcgettext {
    ($domainname:expr, $category:expr, $msgid:expr, $($args:expr),+ $(,)?) => { ... };
}

Like dcgettext, but allows for formatting.

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