you could do "darcs pull -v --dry-run" to see that ;)

Anyway, this may be usuall things for you, when you are in close touch
with all project developers which cat push action to the repo. But for
larger projects you may want to examine all the patches that are on
remote repo.
I agree though that usuall action is "darcs pull -a".

Agree, nevertheless support for #3 is nice to have feature and it is
not so different from #2.
