I quite like the "keep" idea (handy if you have a dataset 
containing a lot of "junk"), and I also like the idea of moving 
"delete" (for variables) into place under the "dataset" command.

The old "delete" command could be kept as an alias, at least for a 
while.

As for deleteobs and keepobs, these seem to me somewhat 
redundant given the smpl command and the ability to save the 
dataset.
