As Dirk said, the argument was that the methods package used to take a 
long time to load, and many uses of Rscript shouldn't have to pay that 
time cost.  I don't know whether that's still true or not.  Dirk and I 
agree that the inconsistency between R and Rscript is undesirable, but 
neither of us is in a position to change it, or thinks it's worth the 
effort to argue for a change.
