(Sorry for the test mail) What I wanted to say is that this long explanation convinced me to write a patch and send it out the next days, >When we are doing "git apply --index", then we _require_ that the >indexed contents and what is in the working tree matches before >applying the patch, so it is perfectly fine to let convert_to_git() >to look at the current index---that is the "previous" one we want to >take hint from while using the safe CRLF logic.
