[PATCH v11 0/8] filter: support for excluding all trees and blobs

[Matthew DeVore <matvore@google.com>]

Here is a clean re-rollup fixing the issue I found earlier. It fixes a problem
stemming from a discarded exit code, which masked a crash in Git. The crash was
not a bug because an earlier test deleted a loose object file. The fix was to
make that test manipulate a clone rather than the original repo.

An interdiff from v10 is below.

Thank you,
Matt
