From: Johannes Schindelin <johannes.schindelin@gmx.de>

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.
