results for SELECT with a TYPEOF only show id/name columns

[superfell]

Run a query using typeof, e.g.
SELECT subject,TYPEOF what WHEN account Then id,BillingCity when opportunity then name,nextStep else id,name end from Task

the results only shows the What.Id & What.Name columns, the additional columns from the typeOf clause aren't displayed.

this is an issue with the code that extracts column names from the results. It assumes that related sobjects are all the same type
