docs: explain what .. etc are shorthand for

Browse source 
`..` is shorthand for `root()..visible_head()`, for example. We don't
seem to explain that anywhere. I hope mentioning that will help
readers understand the relationship between the shorthands and the
full `x..y`, and also to see the correspondence between `..` and `::`
(in how their default left and right operands are the same).
