From: Johannes Schindelin <redacted> The `scalar` command needs a Scalar enlistment for many subcommands, and looks in the current directory for such an enlistment (traversing the parent directories until it finds one). These is subcommands can also be called with an optional argument specifying the enlistment. Here, too, we traverse parent directories as needed, until we find an enlistment. However, if the specified directory does not even exist, or is not a directory, we should stop right there, with an error message.
