query for large object display

[Ben Shoemaker]

Rodney,

Not necessarily.  These are S objects residing in .Data/ that could've
been read from file or created from other S objects.  If I start an S
session, I don't need to open any files if I have a large object already
in my .Data/.  Then if I (accidentally) type the object name at the S
prompt, I get the large dump.
