feature request: gnus-summary-reparent-thread

[<jari.aalto@poboxes.com>]

    Hi,

    In the my private mail and sometimes in mailing lists I want to
    reparent some articles. All goes well as long as the subject stays the
    same, but if subject is not same (while the matter stays same), I
    don't see a nice threading:

    #   Subject-A
        Subject-B
    
    If I hit T ^ now on the last article it won't show up

        Subject-A
          Subject-B
   
    unless I first manually go to  Subject-B and "e"dit the subject
    to be the same as Subject-A and only then hit the T ^

    I'd like to have another command that would do essentially the
    same as T ^; but also it would substitute the child's subject
    with the parent subject. This way the threading would be seen.
    Howabout adding prefix argument to T ^ to accomplish this?

    Or is there something I have missed?
