Ah, right.  But...  the super-confusing thing about this is that we're
not moving point in the buffer at all.  Just doing `M-: 4 RET' will
result in this code adjusting point in the buffer.  Doing, for instance,
`M-x foo RET' (where `foo' does nothing) does not result in this point
movement.

So is `M-:' doing some weird thing in the original buffer to trigger
this oddity?
