Subject: rc: move free carat handling into parser

This fixes at least one shell script (printfont) that expected

	'x'`{y}'z'

to mean

	'x'^`{y}^'z'

as it now does. Before it meant:

	'x'^`{y} 'z'

One surprise is that adjacent lists get a free carat:

	(x y z)(1 2 3)

is

	(x1 y2 z3)

This doesn't affect any rc script in Plan 9 or plan9port.
