Is it "as-designed", or just "left buggy"?

I somehow had an impression that you meant the latter, and it would
be our aspirational goal to eventually fix it.  And for such case,
it would be better to write the test body to show what the command 
should do, which would make the test fail with today's Git, and mark
it as test_expect_failure (which is not an ideal mechanism to prepare
for a future fix, but that is what we have now and should use, until
a better alternative being worked on is finished).

But if it is "as-designed, some users may find it suboptimal or
confusing or with any other negative adjectives, but it is too late
to change now and more importantly it is unthinkable to change it
because existing tools and users do depend on the current behaviour",
then what you did is perfectly fine.

That, too.

Thanks.
