Color reports, html reports, all that is 1%. The largest problem we face with 
dmd -cov is simply getting people to use it as a matter of course. I know that 
it is not being used pervasively because when I run Phobos unit tests with -cov, 
large swaths of code are not tested.

dmd -cov=nn will also cause the generated executable to exit with an error if 
the coverage is below nn%. I'd like this to be part of the the autotester so 
that backsliding can be detected automatically, but that's not on dmd, it's on 
how the test suite is put together and scripted.
