Level 3 was intended as a transition to GDB/MI.  clewn started as VimGDB
and I pointed out to Andrew Cagney that they were using annotations back
then.

http://article.gmane.org/gmane.editors.vim.devel/6069 shows some of that

They also seem not to understand that level 3 annotations are just a subset
of level 2 and think that they are necessary to access GDB/MI.

They could just use level 2 and I don't think they can reasonably complain if
we remove two dysfunctional annotations from level 3.
