I'm the opposite color of bikeshed - 'val ? true : false' feels
over-verbose, compared to the shorter '!!val'; and we already use the
short form elsewhere in the code base so it is somewhat idiomatic.  But
like John, I don't care about the paint color enough to dictate which
way you go.

Generally, for Red Hat copyright lines, I only use a range if there is
at least one @redhat.com authorship during each year of the range; alas,
for this file, it was created during a split in 2011 (so earlier years
come from its earlier history in other files) and 2 commits in 2012, but
nothing in 2013.  I don't think we are in any legal trouble by including
2013, but I wouldn't add it in my own workflow.

Other contributors may have different rules for when they add copyright
years; I treat those as something I will not modify, whether they are
right or wrong (although I do try to point out suspicious use in reviews
if I notice it).

I'm also starting to be of the opinion that if anyone ever takes this to
court, the git log will be of much more use than actual years listed in
any given file :)
