[PATCH v2 0/5] Check replacement object type and minor updates

The only changes compared to the previous version are those suggested by Johannes:

- the error message is now:

	"Objects must be of the same type.\n"
	"'%s' points to a replaced object of type '%s'\n"
	"while '%s' points to a replacement object of type '%s'."

- the test uses "." instead of "'\''"

Only patchs 1/5 and 3/5 were changed.

Christian Couder (5):
  replace: forbid replacing an object with one of a different type
  Documentation/replace: state that objects must be of the same type
  t6050-replace: test that objects are of the same type
  t6050-replace: add test to clean up all the replace refs
  Documentation/replace: add Creating Replacement Objects section
