Uhm, not really -- the problem is that every time ibuffer-redisplay is
called, the order is inverted...  since there is no explicit `recency'
sorter.

I've now added such a sorter, and that fixes the problem.  However, this
effectively reverts e782065477917c10759d618e43b2ec18330ffae3, which made
calling `ibuffer-do-sort-by-recency' twice (permanently) reverse the
sorting order...  which I think is pretty odd, since there's already a
command for that.
