Thanks.

Having to change this line every time the test input (or output) has
changed is somewhat unfortunate.

Also I noticed that "word_diff" shell function has this:

       test_must_fail git diff --no-index "$@" pre post >output &&

which solicits two comments:

 - We do not seem to document that --no-index implies --exit-code, ever
   since the latter option was introduced at 41bbf9d (Allow git-diff exit
   with codes similar to diff(1), 2007-03-14).  Probably we should.

 - This assumes that no test vector would have identical pre/post pair
   that expects no output, which feels somewhat limiting.

What we care about in this test is that "git diff --no-index" does not die
an uncontrolled death, so test_might_fail may be more appropriate.

Here is another that probably should be squashed to this patch together
with 3/3 to add tests for the perl driver (I noticed it only because 2/3
had trivial conflict due to recent addition of it).
