I considered that (and also had a version where I simply insisted on a @
being present), but that means the user no longer would get prompted
about the cases where the address was just slightly obfuscated, e.g. the

Cc: John Doe <john at doe.com>

cases, which would be a regression, I guess. So I do want to pass such
cases through, and have them be dealt with when process_address_list
gets called.

So this is just a rather minimal and simple heuristic, which should
still be able to handle the vast majority of cases correctly, and at
least almost never exclude anything that might have a chance of becoming
a real address.
