diff -a doesn't do what I need. Normally I avoid sed/awk :), but that's
not bad. However, it isn't working like I'd expect.

sh-2.01$ echo "fred\ wuz\ hier." | sed s/\\\ /\ /
fred\ wuz\ hier.

Two backslashes give me an error about an unterminated s. 

I would still prefer ways to get "find" and "tar" to use the same method
for printing unprintable characters and spaces at the same time.

Thanks for the pointer,
