Answering my own question... obviously the \*(Ba is being re-written as 
a pipe and inherits the pipe's behaviour, which is what is causing the 
issue (being a pre-defined string and not a special character, which I 
failed to notice).  This seems to be a compatibility issue with older 
groff and thus not a bug.
