[PATCH 1/3] t7300: add tests to document behavior of clean and nested git

["Erik Elfström" <erik.elfstrom@gmail.com>]

Signed-off-by: Erik Elfström <erik.elfstrom@gmail.com>
---

These tests were added so that I could understand the corner case
behaviors of clean and nested repositories and document the changes in
behavior that this series will cause. The ones marked as expect
failure will be changed to expect success later in the series.
