Typically it's a slightly sloppy value.  E.g. (1- pos) or (1+ pos) or
just `pos' but where that position was valid in the past and some
buffer changes may have rendered it invalid.

So it typically is a valid position in 99% of the cases, but I know that
it's not guaranteed to be so in 100% of the cases.
