I wonder how much use the `cc` request actually got, historically, because
DWB, Heirloom, and groff all agree that the following is well-formed:


.cc @
@de XX YY
@  tm hello, weird control character!
@  do tm .br=\n[.br]
.YY
@XX


And that this isn't.


.cc @
@de XX YY
@  tm hello, weird control character!
@  do tm .br=\n[.br]
@YY
@XX


What gives?
