Ancestors: Kernel-eem.1209

Have printInstructionsOn: (but not printInstructionsOn:do:, which is used by the explorer) print nested full blocks indented inline, for compatibility with the behavior for embedded blocks.

  My instances can print the object code of a CompiledMethod in symbolic format. They print into an instance variable, stream, and uses oldPC to determine how many bytes to print in the listing. The variable method  is used to hold the method being printed.!
