I think this is a holdover from pre 2.3 days. Possibly it can be dropped altogether.

fa7d8f955a WIP Python-2.6 but don't remove opcodes 
The scheme for turning 2.6 bytecode into 2.7 psuedo bytecode
I think is a lose.

I won't work for fragment handling.

Instead, change the grammar and syntax rules

This also has the benefits:

* We see how code generation changed over releases
  by looking at grammar and semantic rules rather
  than arbitrary code
* We can better assocate with what's running
  (in a sense this is a restatement of broken fragment
   handling)
* With the right structure in place we are in a better position to
  handle 2.5, 2.4, etc. That is, after a while, the incremental changes
  to get say from python 2.3 bytecode to python 2.7 are great.

982a6010a1 WIP 2.6 redo bytecode handling 
Don't try to convert 2.6 bytecode to 2.7 psuedo bytecode.
Instead adjust grammar and semantic actions.

Down the line we should to segregate version changes in
semantic code better.

a08ece371e pydisassemble improvements; DRY scannners 
disas.py:
 - disassembles *all* code objects found

scanner*.py:
 - no longer need to pass in version numbers; this
   is obtained from the class name
 - no longer pass in opcodes; this is done at
   initialization from the scanner name
 - all Pythoin 3 scanners support native disassembly

6bc425b45e marshal.py: Python2 marshal code shouldn't try to turn a code object 
into a string. parse3.py: handle both keyword and positional function
calls. scanner34.py: Remove extra level of quoting in LOAD_CONST.
Keyward handling now works cross Python 2/3. Some other spelling and doc fixes.

bytecodes in a code object.
