I think you got faked, but not by me.  My original question was how to
do this in Perl, and that "normal" method is still my preference.  Tom
Phoenix suggested the pipe in one of the early replies and it's a nice
solution -- and end-run around the problem.

It's not even command substitition - the PROMPT_COMMAND line is in my
.bashrc :)
