git diff – show me line ending changes?

First, make sure you’re using the coloured output (e.g. with git diff --color) and that you’ve enabled whitespace highlighting with (e.g.)

git config color.diff.whitespace "red reverse"

This might not work in all cases, however, as git doesn’t appear to highlight trailing whitespace for removed lines. To see whitespace that you’ve deleted, simply use

git diff -R

to put the whitespace on the ‘added’ side of the comparison, where it does get highlighted.
