Yes, this should yield the same.

You could try .gitattributes to exclude files from crlf conversion. But I'd not recommend this, because the mechanism has some deficiencies, as discussed in

This is the way to go.

For cross-platform projects, I recommend to explicitly configure autocrlf on Windows and Unix. On Windows set

    git config core.autocrlf true  # on Windows

and on Unix set

    git config core.autocrlf input # on Unix

This ensures that the repository only contains LF. Even if someone emails source code from Windows to Unix and commits it there.
