Comment:

 Sorry, I think we need a different target name for this new "reset-gcov"
 semantics, if that's what we're going for.  In the current semantics,
 running 'reset-gcov' after a test run resets the coverage, but doesn't
 stop you from running "make check" again.  But if we change it to remove
 the gcno files too, that will means that you need to do a full "make
 clean" and "make" before you can run the tests for coverage again.
