Signed-off-by: Olivier Brunel <jjk@jjacky.com> --- Hey, Some background regarding this: I've written a little tool (kalu, [1]) which is an upgrade notifier, and also features a GUI/frontend for the sysupgrade (-Syu) operation. Whenever there was a pacnew installed, I would open a terminal and run vimdiff on the files; I would also wonder if it wouldn't be nice to have a third file featured, the "original" one (i.e. from the previous package). And so I started wondering about kalu making a list of all pacnew files created during the upgrade, as well as the name & version of the old package, so that I could use a little script to extract the file and start the 3-way diff. (kalu allows to execute one or more command lines after the sysupgrade completed, so this list is just a variable parsed on said cmdlines.) This all works well, but to make that list, kalu would have to e.g. use a regex to extract the pacnew filenames from ALPM's warnings, and that's just not a very good or reliable thing, especially when you know such warnings are translated. Hence, why adding a couple events (there's pacorig as well) in ALPM makes everything much better & simpler; And knowing about such events could be useful to some frontends, even though pacman obviously has no use for it (atm). So, I'm hoping you'd be willing to merge this.
