Oooh dang... I missed that one when doing the interactive git-add...

Obviously so, yes.

Well, I'm not too sure either. We have two coflicting rules here:

  - one package per-line, so that we can add/remove packages without
    touching the existing lines, so if we were top add a package after
    the last one, we'd have to touch two lines,

  - we almost exclusively put the && at the end of a line...

Note that the docker best practices put the && at the beginning of the
line when they need to split lines.

So, I don't care what rule we apply (as I prefer neither, as I favour
the one in the docker best practices).

Yann E. MORIN.
