Coding style and else statements

The and ... or trick is buggy (what if thing == -1?) and bad style. If
you -do- want a conditional expression, 2.5 provides one:

thing + 1 if thing else -1

No subtle logical bugs, and a good deal more obvious.

On the topic of the original posting, I personally prefer the latter
(no else clause), because too deep a level of indentation is not a Good
Thing. However, if a redundant else: would make the code clearer
somehow, by all means use one, because this is more a matter of
personal taste than anything.
