I heavily disagree with this, well-formatted code is a great way to improve software quality, since it improves readability and reduces the chance of mistakes. If you are worried about complicating history, what you would ideally do is have a CI check or a pre-commit hook (idk if that exists in Fossil) to automatically run formatting tools, so that useless trailing spaces never get into the repository in the first place. In fact, it would also be nice if something like clang-format was enforced too, but it's not my place to tell you how to format your code, and clang-format isn't related to my immediate problem of diffs on SQLite files caused by format.sh.
