Because "--graph" is about connected history while --no-walk is about discrete points, it does not make sense to allow these two options at the same time. [1] This change makes a few calls to "show --graph" fail in t4052, but asking to show one commit with graph is a nonsensical thing to do. Thus, tests on "show --graph" in t4052 have been removed [2,3]. Same tests on "show" without --graph option have already been tested in 4052. 3 testcases have been added to test this patch.
