obsoleting the annotate level 2 interface

I glanced at DDD.  The most recent DDD is DDD 3.3.1, released 2001-05-02.
It has a "-fullname" option which it passes down to gdb.  ddd/GDBAgent.c
has code to discard any annotation-2 output coming from gdb:

  # ddd/GDBAgent.c
  case '\032':
      // In annotation level 2, GDB sends out `annotation'
      // sequences like `\n\032\032prompt\n'.  Future DDD
      // versions might want to look at these annotations; right
      // now, we simply weed them out.

There's similar code for the annotation-2 prompt.  I didn't see any code
in DDD 3.3.1 to turn on annotation, it just wants to ignore any
annotation-2 that the user turns on.

The CVS version of ddd/GDBAgent.c (from sourceforge) still has this code.

http://www.gnu.org/software/ddd has links to several other front ends,
including: gvd, insight, kdbg, xxgdb, tgdb, xwpe.

Let me know if it would be useful to chase all these projects down and
report on them.
