Don't think that this is a new feature ...

Anyway, fixed now.  Nevertheless, the idea of also looking for data sets
in the working directory needs rethinking.  Do we really want this?  If
so, then e.g. we need to fix warnings if there is a data dir but no
index (the working dir is not simply a `package' ...).
