File data is lost because the index version of the files has been changed but there is nothing that is in the working directory. This will cause the next 'git status' call to show either deleted for files modified or deleting or nothing for files added. The added files should be shown as untracked and modified files should be shown as modified. To fix this when the reset is running if there is not a file in the working directory and if it will be missing with the new index entry or was not missing in the previous version, we create the previous index version of the file in the working directory so that status will report correctly and the files will be availble for the user to deal with. This fixes a documented failure from t1092 that was created in 19a0acc (t1092: test interesting sparse-checkout scenarios, 2021-01-23).
