You are right---piglit doesn't currently test glEdgeFlag.  I think Eric
was asking if you could please write a new test for piglit that
demonstrates the failure.  The rest of the community doesn't have access
to closed source test suites like oglc, but everyone can run piglit.
Having the test will help other developers avoid accidentally break
glEdgeFlag support in the future.
