On Windows, when I run

jupyter nbconvert --to notebook --execute --inplace "Untitled25.ipynb"

it uses CRLF line endings, but when when I open and save it directly via Jupyter notebook or Jupyterlab it always saves with LF line endings.

I think that the best solution would be to match the behaviour of Jupyter notebook, i.e. replace the line endings with LF. Alternatively, it should maintain the existing line endings, rather than (presumably) always using "native".

nbconvert 5.5.0, notebook 5.7.8, pandoc 2.7.3, juptyerlab 1.0.1
