I remember I had a problem once with git doing automatic LF->CRLF on
Windows. The solution was to

> git config --global core.autocrlf input

You may or may not want to leave out the --global flag here.

Another possibility is then that the wrong perl program is being picked up - Windows strawberry perl would add CRLF. If you type    which perl    in WSL does it look right?
