default-peg-grammar lacks * and + versions of :A, :D, :H, :S, and :W

Unlike :a, :d, :h, :s, and :w, the "capitalized" versions (negations - e.g. :A) in default-peg-grammar lack * and + versions:

janet/src/boot/boot.janet

Lines 2333 to 2355 in cc5beda

	(def default-peg-grammar
	`The default grammar used for pegs. This grammar defines several common patterns
	that should make it easier to write more complex patterns.`
	~@{:d (range "09")
	:a (range "az" "AZ")
	:s (set " \t\r\n\0\f\v")
	:w (range "az" "AZ" "09")
	:h (range "09" "af" "AF")
	:S (if-not :s 1)
	:W (if-not :w 1)
	:A (if-not :a 1)
	:D (if-not :d 1)
	:H (if-not :h 1)
	:d+ (some :d)
	:a+ (some :a)
	:s+ (some :s)
	:w+ (some :w)
	:h+ (some :h)
	:d* (any :d)
	:a* (any :a)
	:w* (any :w)
	:s* (any :s)
	:h* (any :h)})

I suspect that on some occasions some of us have missed :S+ or similar.

May be it makes sense to "complete" the set?

Looks fine to me
