Allow option to show only not run faces

[gopar]

Awesome package! :)

Looks like there is not way to only show the cov-coverage-not-run-face? Personally I don't like seeing cov-coverage-run-face as I find it distracting and I looked at the code and it seems that there is no way to turn that part off.

Would be nice that have that option :)

Thanks!

You can always define cov-coverage-run-face to nothing.
