Contributions summary:Doug primarily focused on improving the `ugrep` codebase, addressing newline handling and output formatting. They implemented more efficient CR removal using `memchr` and `memmove`, enhancing performance. Further contributions included setting `stdout` to binary mode and correctly outputting "\r\n" on Windows, fixing exceptions in pipes, and ensuring correct newline behavior. They also added support for `cpp` as a valid file type.
