:/usr/bin/html2ascii/html-to-ascii.pl /tmp/$$.html|pr
:rm /tmp/$$.html

I don't see how that ever worked. Try changing the link to

ln -s /proc/$$/fd/0 /tmp/$$.html
^^

In the original, the link doesn't resolve to the same place for the
child process as it does for the parent shell since "self" has changed.
