[PATCH 1/2] lib: Use email address instead of empty real name.

[Jesse Rosenthal]

Currently, if a From-header is of the form:

    "" <address at example.com>

the empty string will be treated as a valid real-name, and the entry
in the search results will be empty.

The new behavior here is that we treat an empty real-name field as if
it were null, so that the email address will be used in the search
results instead.

Subject: [PATCH 2/2] test: Add test for correct naming of author.

This is a new test file, since handling of unusual email addresses
doesn't seem to fit well in any of our existing tests.
