Oh. Hey, that's neat; I didn't know about that one. So Kenta could
-- possibly -- do this:
grep -o -E [[:xdigit:]]+
However, that will generate false positive matches on anything that
happens to match a hex digit and isn't within Kenta's field delimiters
(colon and backslash). May or may not be an issue, depending on what
"foo" and "bar" really are. And you can't use any kind of delimiter
matching without also including the delimiters in the output with
grep, can you?
