OK, re-rolling this.

Sounds like a nice idea.

Hah, I should trust my first instincts more; my first version of the
patch dropped the "TODO", but then I put it back in because I thought
people would object :-)

I would challenge the assumption that the test passed because someone
deliberately fixed the code it was testing. Whilst this is a probable
scenario (e.g. if they forgot to adjust the test to expect success
rather than failure), it's not the only one. Tests can be brittle and
depend on external factors which can change unexpectedly. For
example, I noticed that the final 'general options plus command' test
in t9902-completion.sh is currently dependent on the contents of the
current $PATH. This is because I have a shell-script called
`git-check-email' on mine, so `check-email' becomes an extra
subcommand completion possibility for the prefix `check'. Almost
every other developer running this test would not encounter the same
failure. It's not a huge stretch to imagine a similar corner case
which could unexpectedly cause a test to pass when failure was
expected.
Therefore I would suggest a wording which avoids implying that
something was deliberately fixed. That was my reasoning behind
introducing the word "vanished" to the output.
