Fix manual formatting

Few issues...

  * Malformed ReducedExitPolicy, causing brackets to appear.

  * ExitPolicyDefault wasn't actually listed, instead it munged the description
    into the ExitPolicy description.

  * Extra plus signs in the ExitPolicy and ReducedExitPolicy entries. After an
    hour of struggling with asciidoc couldn't figure out how to format it as
    'paragraph => example => paragraph with same indentation' so just
    rearranging the ExitPolicy entry.

    Patches welcome if someone strongly prefers having the paragraph after the
    example.
