I originally rolled back the question because I thought the author's inclusion of the reference to Code Complete had stood the test of time without needing to be removed. At this point, the question is over two years old and nowhere in the history of edits prior to revision 14 did anyone attempt to remove the reference to Code Complete.
I would agree that the inclusion Code Complete in the question could make it "not neutral," but I'm not sure that is enough justification to remove it. The reference to this book also serves as an example of what kind of answer the author is looking for. Providing an example adds value to the question, even if it does appear to add "bias."
For me, the biggest justification for leaving it in is that I didn't feel that my judgment of whether or not the text should be removed was more valuable than the community's judgment that the text's removal was unnecessary, as evidenced by the fact that it has remained in place for two years. If the 1885 users who have favorited this question have not previously thought to change it in this way, perhaps I shouldn't either.
Granted, just because something stands the test of time doesn't mean it is right, but it should weigh in to one's decision-making.
