This sort of works interactively, that is it finds most of them. Blah is
missing a final parenthesis and I don't understand if addresses with 2 d's
is outside the scope of the let or not. Anyway, it just returns a list of
nils even if some email addresses are below the point of invocation in
*scratch.
\b[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]\{2,4\}\b
Maybe all of the backslashes have to be doubled.
