%IF{" istopic '' " then="Oh No! Empty String is a Topic. Arrgh!" else="Oh good; istopic works as expected."}%

Where the bug exists, this renders as: Oh No! Empty String is a Topic. Arrgh!
Here it renders as:

Oh good; istopic works as expected.

Thanks. Fixed in upcoming Foswiki 1.2. See http://trunk.foswiki.org/Tasks/Item13347 for test.

Crawford pointed out that my fix would incorrectly match topic 0000.

But with further testing, topic '0' is also invalid, because normalizeWebTopicName() always returns WebHome if called with topic = 0, so a topic with that name would probably be unreachable.
