In test case "shared=all", the working directory is permanently changed to the "sub" directory. This leads to a strange behavior that the temporary repositories created by subsequent test cases are all in this "sub" directory, such as "sub/new", "sub/child.git". If we bypass this test case, all subsequent test cases will have different working directory. Besides, all subsequent test cases assuming they are in the "sub" directory do not run any destructive operations in their parent directory (".."), and will not make damage out side of $TRASH_DIRECTORY. So it is a safe change for us to run the test case "shared=all" in current repository instead of creating and changing to "sub". For the next test case, the path ".git/info" is assumed to be missing, but we no longer run the test case in the "sub" repository which is initialized from an empty template. In order for the test case to run properly, we can set "TEST_CREATE_REPO_NO_TEMPLATE=1" to initialize the default repository without a template.
