ie, let the mangler enforce empty or a valid directory not ending in a
slash, which is hardly difficult, and makes ROOT easier to work with,
along the lines of how any shellscripter would do it, similarly to the
motivation for the change to D. Only with ROOT it's much more important
that the path is correctly-formed for cross-platform compatibility.
