[Daniel P. Berrangé]

The pdwtags program changed its whitespace formatting for enum
values in release 1.19:

  -        ADMIN_PROC_CONNECT_CLOSE = 2,
  -        ADMIN_PROC_CONNECT_GET_LIB_VERSION = 3,
  -        ADMIN_PROC_CONNECT_LIST_SERVERS = 4,
  -        ADMIN_PROC_CONNECT_LOOKUP_SERVER = 5,
  +        ADMIN_PROC_CONNECT_OPEN                     = 1,
  +        ADMIN_PROC_CONNECT_CLOSE                    = 2,
  +        ADMIN_PROC_CONNECT_GET_LIB_VERSION          = 3,
  +        ADMIN_PROC_CONNECT_LIST_SERVERS             = 4,
  +        ADMIN_PROC_CONNECT_LOOKUP_SERVER            = 5,

Workaround this by telling diff to ignore whitespace changes.
