your selection lacks the final LF to make Rc happy ;-)

a quick and dirty hack would be to always append LF:
exec /usr/local/plan9/bin/rc <{9p read acme/$id/rdsel;echo;}

tested with:
echo foo bar
rc <{9p read acme/$winid/rdsel; echo; }

selecting bare `echo foo bar' (without LF) gives syntax error; selectin=
g whole=20
line works a-OK
