cat -n doesn't handle CRLF newline delimiters correctly #6248
Description
This is with the latest version from github, built locally via cargo build --release --features windows
❯ coreutils printf "hello\r\nworld\r\nthere\r\n" | coreutils cat -n
1 hello 2
world
there
Weirdly, looking at the output via xxd, the CRLF sequence is switched to LFCR...
