I certainly think that would be a good idea.  I thought we had been
insisting on coverage via the regression tests for a lot farther back
than 9.4. though perhaps that was only for newer features and we never
went back and added it for existing capabilities.

What would be really nice would be code coverage information for the
back-branches also, as that would allow us to figure out what we're
missing coverage for.  I realize that we don't like adding new things to
back-branches as those changes could impact packagers, but that might
not impact them since that only runs when you run 'make coverage'.

Thanks!
