-- To iterate over the current1, new1, current2, new2, ... arguments
-- we get an array of tables sorted by number and compressed so that
-- it can be traversed with ipairs. The table format looks like this:
-- {
-- {current = x, new = y, num = 1},
-- {current = z, new = q, num = 2},
-- ...
-- }
-- The "num" field is used to correctly preserve the number of the parameter
-- that was used, in case users skip any numbers in the invocation.
--
-- The current1 parameter is a special case, as it does not need to be
-- specified. To avoid clashes with later current parameters, we need to
-- add it to the args table manually. Although it does not need to be
-- specified, we don't want the module's behaviour to change if a user
-- specifies it anyway.
--
-- Also, we allow the first positional parameter to be an alias for the
-- new1 parameter, so that the syntax for the old templates
-- {{requested move}} and {{move-multi}} will both be supported.
--
-- The "multi" variable tracks whether we are using the syntax previously
-- produced by {{requested move}}, or the syntax previously produced by
-- {{move-multi}}. For the former, multi is false, and for the latter it is
-- true.
