Bug#572033: debbugs: The bug list should display the master bug when bugs are merged
I've merged a few bugs (275949, 382871, 429270, 435562, 443119, 454063,
474690, 544824, 563712 and 572009), making 572009 (the most recent one)
the master bug.
I was expecting it to be the one displayed in the bug listing, but it
isn't. Instead, the oldest bug seems to be the one displayed (275949).
I think it would make more sense to display the master bug and not
another one when repeatmerged is set to no.
