Feature: Display item number in list

[dlants]

I think it's useful to quickly see how many items are in the list. For example, if you're trying to narrow down a regexp (watching the number of matches decrease) or fiddling with a test (hopefully making fewer tests fail).

With a quickfix list, since the lines are numbered, you can go to the bottom of the list (with G) and see the total number of items relatively quickly. Also, while working your way through the list, it's easy to see your progress (have I done 10 of the items or 30?).

It would be nice to have a similar feature in trouble.
