scalar: constrain enlistment search Make the search for repository and enlistment root in 'setup_enlistment_directory()' more constrained to simplify behavior and adhere to 'GIT_CEILING_DIRECTORIES'. Previously, 'setup_enlistment_directory()' would check whether the provided path (or current working directory) '<dir>' or its subdirectory '<dir>/src' was a repository root. If not, the process would repeat on the parent of '<dir>' until the repository was found or it reached the root of the filesystem. This meant that a user could specify a path *anywhere* inside an enlistment (including paths not in the repository contained within the enlistment) and it would be found. The downside to this process is that the search would not account for 'GIT_CEILING_DIRECTORIES', so the upward search could result in modifying repository contents past 'GIT_CEILING_DIRECTORIES'. Similarly, operations like 'scalar delete' could end up unintentionally deleting the parent of a repo if its root was named 'src'. To make this 'setup_enlistment_directory()' both adhere to 'GIT_CEILING_DIRECTORIES' and avoid unwanted deletions, the search for an enlistment directory is simplified to: - if '<dir>/src' is a repository root, '<dir>' is the enlistment root - if '<dir>' is either the repository root or contained within a repository, the repository root is the enlistment root Now, only 'setup_git_directory()' (called by 'setup_enlistment_directory()') searches upwards from the 'scalar' specified path, enforcing 'GIT_CEILING_DIRECTORIES' in the process. Additionally, 'scalar delete <dir>/src' will not delete '<dir>' (if users would like to delete it, they can still specify the enlistment root with 'scalar delete <dir>'). This is true of any 'scalar' operation; users can invoke 'scalar' on the enlistment root, but paths must otherwise be inside the repository to be valid. To help clarify the updated behavior, new tests are added to 't9099-scalar.sh'. Finally, this change leaves 'strbuf_parent_directory()' with only a single, WIN32-specific caller in 'delete_enlistment()'. Rather than wrap 'strbuf_parent_directory()' in '#ifdef WIN32' to avoid the "unused function" compiler error, move the contents of 'strbuf_parent_directory()' into 'delete_enlistment()' and remove the function.
