[Qemu-devel] [PULL for 2.9 28/49] qapi2texi: Generate reference to base type members

[Markus Armbruster <armbru@redhat.com>]

The generated documentation doesn't mention object type members
inherited from a base type.  Fix that.

Example change (qemu-qmp-ref.txt):

  -- Struct: VncServerInfo

      The network connection information for server

      Members:
      'auth' (optional)
	   authentication method used for the plain (non-websocket) VNC
	   server
+     The members of 'VncBasicInfo'

      Since: 2.1
