Message 92485 - Python tracker

This patch could potentially break non-Mac OS X systems.
Fortunately, I have a patch that works with systems that use GNU 
readline and systems that use editline emulation. See issue 6877.

Unfortunately, I was lingering for over a year with opening a tracker 
issue for it.  Last night I did the last testing session with the trunk 
checkout and I did not notice that this issue has been opened in the 
meantime.

Sorry for opening the double issue.
I think that the patch from issue 6877 should be used.
