[PATCH 2/3] t9902: add completion tests for "odd" filenames

[Jeff King <peff@peff.net>]

We correctly handle completion items with spaces just fine,
since we pass the lists around with newline delimiters.
However, we do not handle filenames with shell
metacharacters, as "compgen -W" performs expansion on the
list we give it.

Actually, these vectors are not strictly correct, as I think ultimately
we would like to return

  'name with spaces'

with quotes.  But this lets us test that at least the basics work, and
we can update the test vectors later.

It would be nice to test completion on a file with an embedded newline
(which will also not work), but I'm not even sure what the result is
supposed to look like, so I couldn't write a sane test case. Since I
don't plan on fixing that anytime soon anyway, I think it's sane to just
leave it until later if somebody actually cares.
