[PATCH 0/2] merge-ort: fix a crash in process_renames for a file transitively renamed to itself

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

Maintainer note: this is not a recent regression; it need not be included in
v2.49.0.

This is a follow-up to Dmitry's report of a case where both merge-ort and
merge-recursive fail to properly handle a very specific type of conflict.
See
https://lore.kernel.org/git/20240921024533.15249-2-dgoncharov@users.sf.net/
for the earlier thread; the first patch is an adaptation of his
demonstrating the issue, and the second patch is my fix for it.

Dmitry Goncharov (1):
  t6423: add a testcase causing a failed assertion in process_renames

Elijah Newren (1):
  merge-ort: fix slightly overzealous assertion for rename-to-self
