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.
