Side note: If you ever want to push your repository somewhere,
it would be good practice to have a .gitattributes file:

echo "* text=auto" >>.gitattributes
git add .gitattributes
git commit -m "add .gitattributes"

This can be useful if the repo is pulled to a person who has
core.autocrlf=false, if case [s]he is creating files with CRLF in the
worktree.

As Junio pointed out, it is probably not git diff saying this ?

Typically "git add" gives the warning.

I could agree.
Do you want to send a patch for this ?
(The code to be changd is in convert.c, plus some test cases)
