Windows build number

10.0.22631.5189

Other Software

No response

Steps to reproduce

When copying some printouts from tmux, there are a lot of trailing spaces, and sometimes missing newline chars

https://github.com/vllm-project/vllm/pull/16859#issuecomment-2872065826

E.g. here I had to manually insert newlines (but still kept the trailing spaces for bug demonstration purposes)

Expected Behavior

No trailing spaces, and newline chars preserved when copy-pasting output in tmux

Actual Behavior

trailing spaces and missing newline chars
