btw, that's with the latest python-interactive script (that I could
find) applied (+ the sigint patch too).

For grin's sake, there's another example:

--- snip ---
python
if 0 =3D=3D 1:
  print "foo"
end
---

If I cut-n-paste that into gdb the "end" terminates the "if" block
(heh, didn't expect that :-)), and afterwards I'm still in python.
Maybe this can be fixed too.
