[PATCH 0/3] sparse-checkout: fix segfault on malformed patterns

This series fixes some issues with parsing sparse-checkout patterns when
core.sparseCheckoutCone is enabled but the sparse-checkout file itself
contains patterns that don't match the cone mode format.

The first patch fixes a segfault first reported in [1]. The other two
patches are from an earlier submission [2] that never got picked up and I
lost track of. There was another patch involving 'git sparse-checkout init
--cone' that isn't necessary, especially with Elijah doing some work in that
space right now.
