[0/7] Mostly whitespace changes and fixes.

  Hi.

These are mostly whitespace changes. Let me know if any of them need
a tweak. Apologies in advance for fedabipkgdiff test breakage.

The first patch partially undoes 474ad38f in line with
maennich@google.com's review comments and my original intention.

However, if you prefer the more compact output format for top-level
lists of [C]hanged things, it should be easy to switch to that as all
the places where the different behaviour happens is commented.

The fourth patch touches quite a bit of code which is not covered by
current tests and I wasn't able to exercise.

The fifth patch has semantic changes and warrants more careful review.

This was also me working out how to do hg split with git.

 git rebase -i
 git reset HEAD^1
 git add -p
 git commit -c REBASE_HEAD

Regards,
Giuliano.
