[PATCH v2 00/11] Start preparing merge-related tests to work with multiple merge backends

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

This series starts preparing the merge related tests to work with multiple
backends: merge-recursive or merge-ort. Further work will be coming.

v1 of this series only had the first patch (which collected merge machinery
related tests into t64*.sh). This series adds 10 more patches, which:

Changes since v1:

 * tighten some testcases so they don't pass with completely wrong results
 * fix various errors in causing many test_expect_failure tests to fail for
   the wrong reasons
 * add clarifying comments or fix various comments
 * make some tests more flexible in handling console output messages
   produced by either backend.
 * I'm curious about portability of the second-to-last patch -- is it safe
   to use backreferences with test_i18n_grep? If not, anyone have
   alternative ideas for handling those needed changes?

The greater flexibility patches at the end of the series also previews some
of the design changes being brought by merge-ort.

Elijah Newren (11):
  Collect merge-related tests to t64xx
  t6418: tighten delete/normalize conflict testcase
  t6422: fix bad check against missing file
  t6416, t6422: fix incorrect untracked file count
  t6423: fix test setup for a couple tests
  t6422: fix multiple errors with the mod6 test expectations
  t6416, t6423: clarify some comments and fix some typos
  t6423: add an explanation about why one of the tests does not pass
  t6422, t6426: be more flexible for add/add conflicts involving renames
  t642[23]: be more flexible for add/add conflicts involving pair
    renames
  t6425: be more flexible with rename/delete conflict messages
