cli/reply: reduce the reply format abstractions

Now that we've made the various reply formats quite similar to each
other, there's no point in keeping the abstractions. They are now
close enough to be put in one function.

For now, a mime node will be uselessly created for the headers-only
case, but this is insignificant, and may change in the future.
