[RFC PATCH 0/7] add/rm: honor sparse checkout and warn on sparse paths

This is based on the discussion at [1]. It makes `rm` honor sparse
checkouts and adds a warning to both `rm` and `add`, for the case where
a pathspec _only_ matches skip-worktree entries. The first two patches
are somewhat unrelated fixes, but they are used by the later patches.
