Following my usual review practice of lazy reading for the sake of readers in the future who might be in a hurry, it's not clear what problem these tests are solving or trying to detect. Could you start with a quick summary of the symptoms and when it came up? The commit message doesn't need to paraphrase the actual code, since anyone curious about the details can always look at the code. It's more important to explain the motivation and intended effect so people can understand what went wrong if something ends up being broken by a later patch. > This approach can be used to compute tree merges while checking out only > conflicting files to disk (which is useful for server-side scripts). > Prior to commit 5b448b85 (merge-recursive: When we detect we can skip an > update, actually skip it, 2011-08-11) this worked cleanly in all cases. Do you mean something like the following? Sometimes when working with a large repository it can be useful to try out a merge and only check out conflicting files to disk (for example as a speed optimization on a server). Until v1.7.7-rc1~28^2~20 (merge-recursive: When we detect we can skip an update, actually skip it, 2011-08-11), it was possible to do so with the following idiom: ... summary of commands here ... Nowadays, that still works and the exit status is the same, but merge-recursive produces a diagnostic if "our" side renamed a file: error: addinfo_cache failed for path 'dst' Add a test to document this regression.

As a side effect, that makes the indentation easier to see.
