[Mono-list] [patch] mcs and nested types

Hello Matt!

Thanks for spotting this error.  I have included the above example in
the test suite now.

The fix is gorgeous, and it is the right way of fixing it.  Thanks for
taking the time to research it.  It is not really an obvious fix.

I have not yet commited it to CVS because my tree currently contains
some unfinished code.  I hope to commit the changes tomorrow morning.

Thanks a lot!
Miguel.
