fmt is not platform independant

[ronhippler]

I run deno fmt --check as github action step.
It passed on linux and mac but found 9 not formatted files on windows.

deno v0.40.0

Can you provide more details please.

Sry I have no windows pc.
I would guess fmt wants to change the line endings because it complains about all files.

GitHub actions log... providing some of your log details would be useful. Otherwise we are just guessing. When you say 9 files, those were all the TypeScript files in you code. Can you share a link to the repo? Anything more than "it doesn't work" is helpful.

I created a testrepo and made a few tests.

Deno fmt is not the problem. It converts to LF as expected but the git checkout for github actions uses CRLF as default on windows.

see actions/checkout#135
