Subject: patterns: Allow bare words only in arguments

This changes the syntax from approximately

	expr = unary
	unary = '!'? primary
	primary = pattern | short-pattern | word | quoted-word
	pattern = '?' name [ '(' expr [',' expr]* ')' ]
	short-pattern = ~ name | ~name expr
to:

        primary = pattern | short-pattern
        argument = word | quoted-word | expr
        pattern = '?' name [ '(' argument [',' argument]* ')' ]
        short-pattern = ~ name | ~name argument
