I know, I agree. I've looked at what happens with empty IFSes on $* before, 
which is pretty much the only way I can think of to even test whether the 
words are due to field splitting or parameter expansion. The way bash does 
that is fine. That's probably the least important of these points anyway and I 
wouldn't really expect it to have any impact on these tests involving 
assignments.
