lib.commitIdFromGitRepo now resolves the refs from the parent repository in case the supplied path is a file containing the path to said repository. this adds support for git-worktree and things alike. see gitrepository-layout(5). this also: - adds a new boolean function lib.pathIsRegularFile to check whether a path is a regular file - patches lib.revisionWithDefault and the revision and versionSuffix attributes in config.system.nixos in order to support git-worktrees
