This might all be based on a misunderstanding. Using cat on a directory
is not producing useless garbage. For example, try
cat /etc | hexdump -C # UUOC, I know
Section 18.02 in O'Reilly's "Unix Power Tools" (if you don't have it
already, get it) describes this in more detail.
Modifying cat so it couldn't do this would not be an improvement.
I hope this helps, and thanks for giving me the motivation to look it
up.
