Patches applied to Subversion (trunk, pydb and gddd branches).

The test I removed should be redundant, since the number of answers received should always be consistent with the flags set in extra_data.  However, this requires careful updates to the code in several places, which makes comm-manag.C a nightmare to maintain.

In particular, the flag extra_data->refresh_frame was overlooked in the PYDB case.  A further patch is necessary to fix this.

(file #16897)

The attached patch removes an if (...) test and fixes this particular problem for me.

I'm pretty sure the test should be qu_count >= 0, not > 0, and having made that change it becomes redundant (always true).

In pydb branch, as of Fri Nov 21 2008, running GDB as inferior debugger.

If I start ddd and issue the command "set print static-members off", DDD crashes with the following assertion failure:

comm-manag.C: In function `void extra_completed(StringArray&, const VoidArray&, void*)':
comm-manag.C:3337: assertion `qu_count == count' failed

ddd-3.3.11 does not crash here.  Copying the old comm-manag.C from ddd-3.3.11 fixes the crash, so the bug appears to be related to that file.
