Hi, sorry but I screwed up my previous mail. This is my first patch and the first time I submit a patch to a mailing list.
Now that I know how to add an introduction before sending a patch, let me explain a bit. When taking a look to the test suite of the standard library I found what I believe it was a missing test case. I do not think this is intentional. Because I believe the change is trivial (famous last words) I just provide the patch. I run the tests for 18_support for unix and they were passing. I read quite a lot of documents about contributing, but I might have miss some part. If that is the case let me know and sorry for that. Bests, Xavi
