In Emacs 21 it's probably possible to use the 'display' text-property
for this.  I think it's possible to display an image instead of the
text, but I don't know the details.  Another possibility is Luke's
pretty-lambda[*] hack.

The string-replacement approach is probably less work and also works
in other Emacsen.
