Changes since v6:
1. Fix word wrap in commit message.
2. Use 'mkdir -p folder1' since full-checkout already have folder1.
3. Use `--stat` to ignore file creation time differences in unrefreshed
index.
4. In 'diff-files with pathspec outside sparse definition' add
'git diff-files "folder*/a" to show that the result is the same with a
wildcard pathspec.
5. Create an 'ensure_expanded' to handle silent failures.

<pathspec> contains wildcard that may need a full-index or the
<pathspec> is simply outside of sparse-checkout definition.
- Remove full index requirement for `git diff-files`
- and add test to ensure the index only expanded when necessary
