The argument for changing this would be consistency, but if you want
to argue for it on those grounds, you'd need to change *every* command
that acts that way. I really doubt EXPLAIN is the only one.
There's also a theological argument to be had about which
behavior is preferable. For my own taste, I like last-one-wins.
That's extremely common with command line switches, for instance.
So maybe we should be making our commands consistent in the other
direction.
