Looks pretty nice.

Perhaps the config syntax could be arbitrary_key:attr = value.

  hatebin:fileset = binary()
  hatebin:revset = keyword(binary)
  hatebin:cc = hates-binary-files at example.com

fileset and revset can be quite long. We wouldn't want to write them as config
keys.

And I prefer using matcher patterns instead of fileset for consistency with
the other commands.
