That loop skips ignored changes before function context -- we don't want those. t4015.85 only has an ignored change within function context and 0bb313a5 reveals it, as intended. So for better test coverage we could do something like this. Does it help? (It should, but I'm mystified why 223 shows up in the report.) -- >8 -- Subject: [PATCH] t4015: improve coverage of function context test Include an actual function line in the test files to check if context is expanded to include the whole function, and add an ignored change before function context to check if that one stays hidden, while the originally ignored change within function context is shown.
