That's a good suggestion, but unfortunately not quite trivial:  the code 
that prints that message has no idea what the full filename is.  On 
Unix, R just tries to open ".Rdata" without ever expanding the name, and 
on Windows, the full name is stored in a place that this code can't see.

So it's not impossible to fix this, but it would take some rearrangement 
of things.  I'm busy on other things so I'm not going to volunteer to do it.
