[PATCH] mailinfo: better parse email adresses containg parentheses

["Philippe Bruhat (BooK)" <book@cpan.org>]

    When using git-rebase, author fields containing a ')' at the last
    position had the close-parens character incorrectly removed
    because the From: parser incorrectly matched it as

        user@host (User Name)

    (removing parentheses), instead of

        User Name (me) <user@host>
