Perhaps this is a way-out. As usual, everything is feasible when we resort
entirely on our own code.  The danger is that we might make use of some 
package (may be written some years ago) which assumes drop=TRUE is the default
behaviour, and changing the default behaviour might (potentially) have 
disasterous effects.

best wishes, Adelchi
