The go/ast package uses and guarantees nil slices for optional elements that weren't present in the parsed source code, such as the list of return values of a function. Packages using go/ast rely on this attribute and check for nils explicitly. One such package is go/printer. In the presence of empty slices instead of nil slices, it generates invalid code, such as "case :" instead of "default:". The issues that this CL fixes are all manifestations of that problem, each for a different syntactic element.
