Now for CallTipWindow.py:

* split conditionals into two lines as requested
* changed the test (took me a while to understand what "controversy" you
were referring to...)

I couldn't find anything wrong with the first line. It is the
function/method signature if it was found, or just the beginning of the
doc-string otherwise. Unless you think the adding the signature (when
possible) is unnecessary/confusing...

The above changes are included in both new patches.
