CR likely stands for "CentsRaidensnake." Like the Case Cafe mega-merge
before it, this was not a clean merge, and it had to be split up into
two parts: the actual changes, and the attempt it made to reformat the
entire code via clang-format.
This branch had a complicated set of changes that would be difficult to
describe in this commit message. It would be better described in a
proper changelog.
