cat -n doesn't handle CRLF newline delimiters correctly

[pfmoore]

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...

❯ target\release\coreutils printf "hello\r\nworld\r\nthere\r\n" | target\release\coreutils cat -n | xxd
