Thanks for the credit, but as my recent attempts to fix 2 obvious
deficiencies in Git CI (one of them being my own) failed quite
miserably, I figure I have no idea how these things in CI are to be
treated, so I prefer to leave a fix to somebody else, who actually groks
what makes sense in the Git UI, and what doesn't.

That said, in case you still need the test with expect_success, below is
one rerolled.

Thanks,

Subject: [PATCH] t4013: add test for "log --patch --no-patch"

--patch followed by --no-patch is to be a no-op according to the "git
log" manual page. In reality this sequence breaks --raw output
though (and who knows what else?)

Add test case for the issue.
