Hello,

Originally this bug was reported in the Git for Windows project and contains two screenshots: https://github.com/git-for-windows/git/issues/3321 Johannes Schindelin (dscho) is convinced that this is not a Windows-specific issue. Following is a brief description of this bug as I've faced it:

After running the "git submodule set-branch --branch master -- ms1" I've noticed that the .gitmodules file is encoded with both DOS and UNIX End-of-Line characters simultaneously: all original lines use DOS EOL characters but the added "branch = master" line uses UNIX EOL.

Found on the following environment:

$ git --version --build-options git version 2.32.0.windows.2 cpu: x86_64 built from commit: 3d45ac813c4adf97fe3733c1f763ab6617d5add5 sizeof-long: 4 sizeof-size_t: 8 shell-path: /bin/sh feature: fsmonitor--daemon

$ cmd.exe /c ver
Microsoft Windows [Version 10.0.19042.1083]
$ cat /etc/install-options.txt
