I have a preliminary patch for this. I am not really happy with the C code I wrote for doing the substitutions, but it works.

Does it make any sense to have this for -R and -U operations ? I implemented that but I don't really see any utility so I wanted to drop it.

I think it makes sense for -R at the moment. It would also make sense for -U if -U could handle dependency resolution. If you have working code then I think you should just leave it in for now as it will be good to have later.

Final concern : do you think this feature is useful when pacman asks questions and prints a lot of stuff before the actual output ? For many operations, the output is quite crap, and I don't know how to fix this.

Hmmmm... that's a good point. It might seem superfluous but I think it's good to keep that. It would enable scripts to handle the dialogue through a pipe and then easily parse the output so I see a utility in it. It would probably be less useful for the user directly though, but even then it would be interesting for some dialogues to see which dependencies some of the group members will pull in (or cascadingly remove). Consider the DE groups for example. They should pull in other packages that are not part of the group dialogue.

That does not go well with my idea that print operations should imply noconfirm though (see attached patch and commit log). I guess this requires further thinking and discussion. I also forgot to mention that I don't like the group interactivity , but that is another problem.
