;;; args...
-;;; the command arguments. There are restrictions on the
-;;; 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:
-;;; - no argument
-;;; - markup
-;;; - scheme
-;;; - markup, markup
-;;; - markup-list
-;;; - scheme, scheme
-;;; - scheme, markup
-;;; - scheme, scheme, markup
-;;; - scheme, scheme, markup, markup
-;;; - scheme, markup, markup
-;;; - scheme, scheme, scheme
-;;; This combinations are hard-coded in the lexer and in the parser
-;;; (lily/lexer.ll and lily/parser.yy)
+;;; the command arguments.
+;;; There is no limitation on the order of command arguments.
+;;; However, markup functions taking a markup as their last
+;;; argument are somewhat special as you can apply them to a
+;;; 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
+;;; markup function to a markup list is cheap mostly for
+;;; Scheme arguments, you avoid performance pitfalls by just
+;;; using Scheme arguments for the leading arguments of markup
+;;; functions that take a markup as their last argument.

;;; args-signature
-;;; the arguments signature, i.e. a list of type predicates which
+;;; the arguments signature, i.e., a list of type predicates which
;;; are used to type check the arguments, and also to define the general
;;; argument types (markup, markup-list, scheme) that the command is
;;; expecting.
;;;
;;; category
;;; for documentation purpose, builtin markup commands are grouped by
-;;; category. This can be any symbol. When documentation is generated,
+;;; category. This can be any symbol. When documentation is generated,
;;; the symbol is converted to a capitalized string, where hyphens are

;;; property-bindings
;;; this is used both for documentation generation, and to ease
-;;; programming the command itself. It is list of
+;;; programming the command itself. It is list of
;;; (property-name default-value)
;;; or (property-name)
-;;; elements. Each property is looked-up in the `props' argument, and
+;;; elements. Each property is looked-up in the `props' argument, and
;;; the symbol naming the property is bound to its value.
;;; When the property is not found in `props', then the symbol is bound
-;;; to the given default value. When no default value is given, #f is
+;;; to the given default value. When no default value is given, #f is
;;; used instead.
;;; Thus, using the following property bindings:
;;; ((thickness 0.1)
;;; ..body..)
;;; When a command `B' internally calls an other command `A', it may
;;; desirable to see in `B' documentation all the properties and
-;;; default values used by `A'. In that case, add `A-markup' to the
-;;; property-bindings of B. (This is used when generating
