I'm indeed opposed to showing the whole command because it's too long,
making the output even harder to read (in the "normal" case where
you're looking for byte-compiler errors and warnings).

But it could be improved in 2 ways:
- change the current output so it give less the illusion of being
  a real command.
- provide some option to show the real command.

As for Nicolas's suggestion to "disable" ~/.emacs.d/elpa, I think it
makes sense, since we already use --batch which disables ~/.emacs.
So feel free to install his patch.
