[pacman-dev] [PATCH] Improve transaction summary appearance

[Carson Black]

I'm aware that the quality of appearance is quite a subjective matter,
which is why I kept the changes evolutionary rather than
revolutionary.

C really isn't my forte, but this hasn't segfaulted for me (yet) and I
think the code is mostly memory safe after looking over it.

The changes being demonstrated with colours:
