[issue24840] implement bool conversion for enums to prevent odd edge case

[Gregory P. Smith]

Gregory P. Smith added the comment:

lets collect some examples of where it causes problems (someone ran into the problem at work which is why i hunted down this bugs.python.org issue) before deciding.

If it stays in, it needs a mention in both Misc/NEWS and What's New as it will require some people to test and update their code for 3.6.  Examples will let us decide which way to go.
