The problem is that it doesn't really do what LogFormatter.short_author
needs:

In [2]: email.Utils.parseaddr('John Smith')
Out[2]: ('', 'John')

I don't know whether it's a bug or a feature, but either way it doesn't
work for us.

I personally find "or" clear enough when selecting from the first
non-empty of two values, but I can change it if decide about the first
issue.
