DVC CRLF issue

DVC version: 1.7.2 (pip)
---------------------------------
Platform: Python 3.6.9 on Linux-5.3.0-28-generic-x86_64-with-Ubuntu-18.04-bionic
Supports: All remotes
Cache types: hardlink, symlink
Cache directory: ext4 on /dev/nvme0n1p5
Workspace directory: ext4 on /dev/nvme0n1p5
Repo: dvc, git

Cache is committed to the repo so it can be viewed

Reproduce

• init git and dvc
• create a script.sh with CRLF line endings
• dvc add script.sh
• change CRLF ending to LF
• try to add it again, (doesn't detect changes)

Obtained

script.sh is stored with CRLF in cache, so when you run dvc checkout it always comes back to CRLF line endings even if you modify it locally.

Expected

script.sh should keep the original CRLF line endings or at least store the cache content always with LF endings.

Consequences

• CRLF and LF cannot be modified after first commit
• md5 file name doesn't match the file content hash
