exec</dev/tty replaces the shell stdin with /dev/tty, however

	rc -c cmd

makes rc read commands from the string "cmd", NOT from stdin. Therefore
it is irrelevant to rc's parser how you choose to manipulate fd0 in this
case.

I.e., you are conflating "stdin" with "the place rc reads commands from".
