Sure. At the end of this mail is what I have in my local trunk copy
now.

Well, I did checkout that branch (I'm using the Git mirror), but it
seems to include much more changes than `window-use-time' and
`get-mru-window', and the last merge from trunk is from 30. October. You
mean you'd like to merge it into the trunk as a whole in the near
future, so you're looking for more testers?
