[PATCH 0/4] Directory rename detection testcases and rules

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

While testing merge-ort on some real world repositories a little while back,
I found some issues with directory rename detection...some of which were
issues in the current merge-recursive as well. Also, I found that there was
a nice optimization I could use if a new obvious-looking rule was added,
though it has one slight side effect to one corner case. Fixing the bugs and
implementing the new rules is a bit more involved, so for now this series
just updates the rule descriptions and adds or modifies tests to document
the various cases.

Elijah Newren (4):
  directory-rename-detection.txt: update references to regression tests
  t6423: more involved directory rename test
  t6423: update directory rename detection tests with new rule
  t6423: more involved rules for renaming directories into each other
