I've applied this: it's not sensible to leave the repo broken, as it's
apparent that such doesn't elicit any more responses. Patches can still
be rolled back if some other solution turns out to be preferable.


For reference, you can install containers-0.2.0.1 on ghc-6.12 (some
dependencies need to be adjusted), and then check with:

] ghci XMonad/Actions/GroupNavigation.hs -package containers-0.2.0.1

This can work for most libraries, though some dependencies may need
recompiling to use the same versions.
