Add '--cone' flag to 'git sparse-checkout init' to set the config option 'core.sparseCheckoutCone=true'. When running 'git sparse-checkout set' in cone mode, a user only needs to supply a list of recursive folder matches. Git will automatically add the necessary parent matches for the leading directories. When testing 'git sparse-checkout set' in cone mode, check the error stream to ensure we do not see any errors. Specifically, we want to avoid the warning that the patterns do not match the cone-mode patterns.
