[PATCH 6/6] t: check that a pattern without trailing slash matches a directory

[Jeff King <peff@peff.net>]

Prior to v1.8.1.1, with:

  git init
  echo content >foo &&
  mkdir subdir &&
  echo content >subdir/bar &&
  echo "subdir export-ignore" >.gitattributes
  git add . &&
  git commit -m one &&
  git archive HEAD | tar tf -

the resulting archive would contain only "foo" and
".gitattributes", not subdir.  This was broken with a recent
change that intended to allow "subdir/ export-ignore" to
also exclude the directory, but instead ended up _requiring_
the trailing slash by mistake.

A pattern "subdir" should match any path "subdir", whether it is a
directory or a non-diretory.  A pattern "subdir/" insists that a
path "subdir" must be a directory for it to match.

This patch adds test not just for this simple case, but also
for deeper cross-directory cases, as well as cases with
wildcards.

Added new tests since v1 that handle the match_pathname code path.
