Hard to translate "Displaying %s of %s items" (cannot control the order of substitutions)

[Akihiro Motoki]

horizon/locale/djangojs.pot has the following string.

#: static/framework/util/filters/filters.js:177
#, python-format
msgid "Displaying %s of %s items"
msgstr ""

In some languages, there is a need to swap the order of the two %s.
%s should be replaced by %(keyword)s (keyword substitution).

The current horizon/static/framework/util/filters/filters.js is as follows:

    176 var total = ensureNonNegative(totalInput);
    177 var format = gettext('Displaying %s of %s items');
    178 return interpolate(format, [count, total]);

L.177 should be:

     var format = gettext('Displaying %(count)s of %(total)s items');

    Use keyword substitution in horizon framework filters.js

    Keyword substitution is important for translators.
    It allows them to control the word order natural to their language.
