goto(pos) # absolute
move(incr:int) # relative to current position
negative numbers can be interpreted naturally; for move they go
backwards, and for goto they count from the end.
This would require either a length, or a special value (None?) for at
least one of Start and End, because 0 == -0.
Note that this makes sense for bytes; I'm not sure exactly how unicode
characters even should be counted, without a normalization promise.
