Show changes more clearly if only to line endings (CRLF/LF)

It would be nice if the "git diff" view would show something more prominent if there is a line ending change in a file. Currently we get a blank line with no explanation (with whitespace diff enabled). If it is buried between lines with actual changes, it tends to go unnoticed until CI finds it.

This could be simply a highlight with "<CRLF>" or "<LF>" where the difference was.
