git/t/t3602-rm-sparse-checkout.sh
Matheus Tavares d5f4b8260f rm: honor sparse checkout patterns
`git add` refrains from adding or updating index entries that are
outside the current sparse checkout, but `git rm` doesn't follow the
same restriction. This is somewhat counter-intuitive and inconsistent.
So make `rm` honor the sparsity rules and advise on how to remove
SKIP_WORKTREE entries just like `add` does. Also add some tests for the
new behavior.
