After reading these 3 lines I've no idea what you are talking about. Can
you translate this to English, please? ;-)

Certainly :-)
It means that if you work on a repo with core.autocrlf == true, you'd expect every text file to have CRLF EOLs. However, if you by some operation, get a conflict, then the conflicted file has LF EOLs. Now, of course you'd go about resolving the files conflict, and then 'git add <file>'. When you do that, you'll get the warning saying that LF will be replaced by CRLF. Then you commit. The end result is that you have a workingdir with a mix of LF and CRLF files, which after some more operations may trigger a "whole file changed" diff, due to the workingdir file now having LF EOLs.

 Sorry, no patch to actually *fix* the problem.

Then you should use test_expect_failure instead of test_expect_success.
And maybe also mention it in the commit message.

Well, the test case is written in a way that it *should* pass (iow, it _expects_ a success), but it currently doesn't. So, the goal is that someone, who is more intimate with the code, can just run the testcase until it passes (fixing in between each run, of course ;-)

+test_expect_success 'Check that conflict file is CRLF' '
+	git reset --hard a &&
+	! git merge side &&

	test_must_fail git merge side &&

Ah, I checked a few other testcases, where I saw the ! construct. I don't mind changing it, if it's important. Does it add 'feature' to the testcase by using test_must_fail, instead of '!' ?

+	cat file | remove_cr | append_cr >file.temp &&
+	test_cmp file file.temp
+'
