Module name:	LVM2

Modified files:
	test           : Makefile.in harness.c not.c 

Log message:
	Add a "should" alongside "not" to the test utilities. When a "should" command
	fails, the test will carry on but will issue a warning. The harness detects
	such warnings from tests and marks tests that passed with warnings with a
	special status.
