You can try running "mpg321 -R dummy | grep -v '^@F'" so that
Emacs is not bothered by the other lines.

So it does seem like you use text-properties for invisibility.
One possible reason why the invisible property might get lost when
you copy things around is because of yank-excluded-properties, but
that's an Emacs-CVS thing and that's only if you use kill&yank.

I don't think so.

This is painful to read on my 80-column window :-(

And this plain doesn't show up in its entirety in my minibuffer because my
minibuffer is not resizable and it only ever shows a single line.

Would (with-output-to-temp-buffer "*Help*" (princ "...")) be better, like the

various describe- commands in help.el do?
