-;;;     possible arguments for a markup command.
-;;;     First, arguments are distinguished according to their type:
-;;;       1) a markup (or a string), corresponding to type predicate `markup?'
-;;;       2) a list of markups, corresponding to type predicate `markup-list?'
-;;;       3) any scheme object, corresponding to type predicates such as
-;;;       `list?', 'number?', 'boolean?', etc.
-;;;     The supported arrangements of arguments, according to their type, are:

+;;;     markup list, and the result is a markup list where the
+;;;     markup function (with the specified leading arguments) has
+;;;     been applied to every element of the original markup list.
+;;;
+;;;     Since replicating the leading arguments for applying a
