Comment (by goldfire):

 I'd go a step further than comment:1 and put these kinds of tests in their
 own directory within the `testsuite/tests` directory. Something like
 `unsupp` (or, if you're feeling verbose -- as I often do --
 `would_be_nice`). Then, when I see a failure as I'm putting in a new
 feature, my level of disappointment at failing the testsuite will be
 immediately lowered. Do include a README in the folder describing its
 purpose. Ideally, each test case would also repeat the info that the
 behavior is unsupported.

 I do fully support the inclusion of these tests in the testsuite. Thanks
 for suggesting it!
