    Bug 622822 - Fix failure return from nntp_folder_refresh_info_online()
    
    When invoked with no fmt argument, camel_nntp_command() is only supposed
    to select the folder and return zero.
    
    Since commit 08cfec3e we have been interpreting that zero as FALSE, and
    this is what causes nntp folders to appear empty as refresh_info appears
    to fail.
