Subject: [PATCH 1/3] t3401: add another directory rename testcase for rebase and am
Date: Wed, 29 Aug 2018 00:06:11 -0700
Message-ID: <20180829070613.11793-2-newren@gmail.com> (raw)
In-Reply-To: <20180829070613.11793-1-newren@gmail.com>

Similar to commit 16346883ab ("t3401: add directory rename testcases for
rebase and am", 2018-06-27), add another testcase for directory rename
detection.  This new testcase differs in that it showcases a situation
where no directory rename was performed, but which some backends
incorrectly detect.

As with the other testcase, run this in conjunction with each of the
types of rebases:
  git-rebase--interactive
  git-rebase--am
  git-rebase--merge
and also use the same testcase for
  git am --3way
