Yeah.  It seems like lcov 2.0 is kind of okay (it's working for me
anyway), but the later versions are more broken.  I'm not excited
about changing our docs to reflect that, and definitely -1 on
changing our code.  I think we just have to wait and hope they
get things sorted.

+1, that page seems to be mostly ancient history at present.
