Fetching a single revision returns just metadata by default

Requesting parents works

  $ sendhttpv2peer << EOF
  > command filedata
  >     nodes eval:[b'\x0a\x86\x32\x1f\x13\x79\xd1\xa9\xec\xd0\x57\x9a\x22\x97\x7a\xf7\xa5\xac\xaf\x11']

      ]
    }
  ]

Requesting revision data works
(haveparents defaults to False, so fulltext is emitted)

  $ sendhttpv2peer << EOF
  > command filedata
  >     nodes eval:[b'\x0a\x86\x32\x1f\x13\x79\xd1\xa9\xec\xd0\x57\x9a\x22\x97\x7a\xf7\xa5\xac\xaf\x11']

    {

        [
          b'revision',
          84
        ]
      ],
      b'node': b'\n\x862\x1f\x13y\xd1\xa9\xec\xd0W\x9a"\x97z\xf7\xa5\xac\xaf\x11'

  ]

haveparents=False should be same as above

  $ sendhttpv2peer << EOF
  > command filedata

        [
          b'revision',
          84
        ]
      ],
      b'node': b'\n\x862\x1f\x13y\xd1\xa9\xec\xd0W\x9a"\x97z\xf7\xa5\xac\xaf\x11'

  ]

haveparents=True should emit a delta

  $ sendhttpv2peer << EOF
  > command filedata

    },
    b'\x00\x00\x00Q\x00\x00\x00Q\x00\x00\x00\x03a1\n'
  ]

Requesting multiple revisions works
(first revision is a fulltext since haveparents=False by default)

  $ sendhttpv2peer << EOF
