-- The formatDate method of the mw.language object behaves like the {{#time:}}

-- but outputs garbage when it receives them, behavior inherited from PHP.
-- {{#formatdate:}} magic word is more forgiving.
-- Fix dates so that, for instance, the |date= parameter of
-- {{quote-journal}} (which uses this module) and the |accessdate=
-- parameter (which uses {{#formatdate:}}) accept similar date formats.
