### Please describe the problem.
On my Windows laptop I upgraded to git 2.34 via Scoop and after that two conflict resolution unit tests
started to fail. Presumably this is due to the new `ort` merge strategy that has been made default
in this new release of git. (Ostensibly Recursive's Twin isn't perhaps quite yet what it claims to be.)
### What steps will reproduce the problem?
Install git version 2.34.0.windows.1. Then optionally build your git-annex with `stack setup && stack build`
if you don't have a binary already. Then copy the binary to `C:\annxtmp1` and while situated in said directory
in (Git) Bash say:
```
./git-annex test -p 'conflict resolution ' 2>&1 | tee git-annex..specific-test-01.LOG~202
```
Observe two out of nine tests failing.
`test -p QuickCheck` was fine as were the other v8 unit tests.
### What version of git-annex are you using? On what operating system?
Two versions definitely exhibited this issue: 8.20211029-g9d3ce224e and 8.20211117-gc3af94eff (=released version).
`git-annex version` output of the former below:

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
Yeah sure, I'm a believer. :) Using it with my multigigabyte backup files just fine most of the time.
I'm also building select versions of git-annex for both Windows native and WSL1/2 use following the
development on master. A fine piece of software it definitely is.
