  Sent by #notYetImplemented.  Better than the age-old behavior of opening a notifier window, because this can be caught and handled.

I really need to (a) learn to count properly and (b) figure out a
better way to do cross-package changes.

I think your "n of m" messages are fine. The occasional cut-and-paste
mistake is fairly obvious to us readers of the comments, and not really
a problem. Personally I like being able to just read a set of update
comments like this, mistakes notwithstanding.
