>>ASSERTION A XChangeSaveSet-1
When a call to XChangeSaveSet is made with a change_mode of
SetModeInsert, then the specified window is inserted into
the client's save-set.
>>STRATEGY
Create client1.
Client1 creates win window.
Create test window as inferior of win window using different client.
Call XChangeSaveSet with change_mode SetModeInsert.
Verify that window has been added by destroying client1.
>>ASSERTION A XChangeSaveSet-2
When a call to XChangeSaveSet is made with a change_mode of
SetModeDelete, then the specified window is deleted from
the client's save-set.
>>STRATEGY
Create client1.
Create win window with client1.
Create two inferiors of win window using different client.
Add both to save set.
Remove one of them from save-set with XChangeSaveSet.
Destroy client1.
Verify that window that was removed is destroyed.
>>ASSERTION A XChangeSaveSet-3
When the specified window was created by the same client,
then a BadMatch error occurs.
>>STRATEGY
Create window.
Call XChangeSaveSet with window and same client.
Verify that a BadMatch error occurs.
>>ASSERTION A XChangeSaveSet-4
When the value of change_mode is other than SetModeInsert
or SetModeDelete, then a BadValue error occurs.
>>STRATEGY
Obtain a sequence of values which are not in the list specified by VALUE_LIST.
For each value:
  Call test function with this value in the VALUE_ARG argument.
  Verify that a BadValue error occurs.
