When email is integrated, replies to existing tickets generally find their way to the original ticket and show up as comments, but sometimes they don't. In those cases, it would be very handy to be able to move a ticket, reassigning it as a comment to an existing ticket.

Users with 'administer support' permission will find a new 'Support ticket' fieldset when editing nodes, containing a 'Move' field. Set this to another existing ticket, and the edited support ticket and all of its updates will be moved to become updates to the specified ticket.
