When a tool supports both regular expressions and literal strings, which should be the default? If you default to regex, users can match more strings than they realise (e.g. `foo.txt`) or less (e.g. `foo(bar)`). I typically see regex as the default, but I prefer the opposite.

C++ no longer considers trivial infinite loops to be undefined behaviour! https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2024/p2809r3.html Spotted in the release notes for the latest clang.

Further tinkering with diagnostics, following feedback! * Two lines of context above and below now. * The caret is included in the line below where possible. * Syntax highlighting of keywords. I kinda feel that smart context sizing would be better. What do you think so far?
