ocaml-env seems to change some unrelated file's newline behavior?

[chenglou]

Hello! I'm running your stack on GitHub Action Windows CI, with the current default git settings (checked out files as CRLF). However, it seems that ocaml-env exec -- trivialScript changes some things. The files are still in CRLF but in my setup, git diff is showing a diff, possibly a stale git diff cache (I hardly believe this is actually the case but I've checked all the file's line ending at every step of my commands).

Tldr:

• CI windows git checkout with CRLF
• file.txt still in CRLF
• git diff empty
• run trivialScript
• file.txt still in CRLF of course
• git diff still empty
• run ocaml-env exec --trivialScript
• file.txt still in CRLF
• git diff now shows that there are diffs, but the diff view shows that there isn't any (including, no newline changes. Unless I'm using git diff's options wrong):

  -foo
  +foo
  

I'm unfamiliar with where I can find the source to ocaml-env; do you know what could have happened here?
