Hey Duy,

I'm not sure why the pattern would have to be as you describe - I'm just looking to ignore `*.out` as a general configuration, and disable it for one specific project, so it would seem a plain `!*.out` should work.

In any case, I added a `.gitignore` file with the single pattern `!*.out` at the root of the project, and now .out files are no longer ignored for the project.

It's not an ideal solution because now all the other developers of the project who do not have `*.out` in their `core.excludesfile` will have an unnecessary pattern in their exclusion logic, but it does work as expected.

Thanks, D.
