That's a significant disadvantage; it can easily double the length of
the reported description for a test case.
The Wodget should spangulate with the specified doohickey... ok

(if I have the new description incorrect feel free to correct me, but I
think the point is clear about adding the test name to the description).
Reports that before would mostly stay within a standard 80-column
terminal will now almost always be line-wrapping, making the output much
harder to read.

The problem isn't only with overridden shortDescription. The problem is
the breakage in the existing behaviour of shortDescription, even in
cases that never needed to override shortDescription.

Again, it seems that adding this to the output is the job of the thing
which does the reporting, *if* wanted. The (long!) name isn't part of
the TestCase description, so shouldn't be bolted onto the TestResult
