[PATCH v3 0/7] increase wildmatch test coverage

Fixes issues noted since v2 and one I spotted myself, notes below:

Ævar Arnfjörð Bjarmason (7):
  wildmatch test: indent with tabs, not spaces
  wildmatch test: use more standard shell style
  wildmatch test: don't try to vertically align our output
  wildmatch test: use a paranoia pattern from nul_match()
  wildmatch test: remove dead fnmatch() test code

No changes.

  wildmatch test: perform all tests under all wildmatch() modes

Fix vertical alignment of new test (that was just changed back later in v2).

  wildmatch test: create & test files on disk in addition to in-memory

* Use ${file%/*} instead of forking for finding the dir part of a path

* Consistently name tests, e.g. I had some called wildmatch and
  wildmatch(ls), but then iwildmatch and wildmatch(ls) again, now it's
  iwildmatch(ls) in the second case.
