[PATCH 0/1] reset: fix mixed reset when using sparse-checkout

Original discussion is here https://public-inbox.org/git/20170407192357.948-4-kewillf@microsoft.com/

When running a reset mixed and using the sparse-checkout the working directory needs to be updated so that there is not data loss when the index is updated. This is because the index is getting updated potentially removing entries without changing the working directory. When using the sparse-checkout feature the entries removed might not be on disk and are lost.

This patch writes the before version of the file to disk if the mixed reset is going to change the index of a file that had the skip-wortree bit so that the file contents before the reset is preserved on disk and status will reports the correct results.
