> Some work on S3a has shown up that there aren't tests catching regressions in readFully,
reviewing the documentation shows that its specification could be improved.
> # review the spec
> # review the implementations
> # add tests (proposed: to the seek contract; streams which support seek should support
positioned readable)
> # fix code, where it differs significantly from HDFS or LocalFS
